Attitude

After losing my first two blitz games on a lazy Saturday morning, and then dropping a rook in the third, it would be easy to give in to despair.

Black to move

However, I have been reading Erik Kislik, Applying Logic in Chess (2018). Kislik distinguishes between "mastery-focused (task-based)" goals and "result-focused (ego-based). Result-focused players tend to want to defeat specific opponents and be seen by their peers as winners" (9). He asserts that 90% of chess players are result-focused. He also claims that a task-oriented approach leads to more enjoyment of chess.

Although this blog offers plenty of examples of a task-oriented approach in my study and play, the honest truth of my online blitz and much of my tournament play is that my ego and emotions rise when I win and suffer when I lose. I enjoy chess when I am winning and often play long periods of blitz because I am angry with myself for playing such junk. I nurture this anger with more junk.

I could beat myself up for missing the tactic that led to dropping a rook and likely losing a third game. Or, I could take a fresh look at the board, and see what I can learn about the game. I could resign with dignity, review my errors, and try to play better in game four.

My attitude this morning improved as I remembered what I read last week in Kislik's book, and I finished my morning playing session 2-2. But, the results matter less than the process.

Knights before Bishops

Most chess players have heard the rule that one should deploy a knight towards the center before moving a bishop. The standard move order in the Spanish opening is a good example--for White, a center pawn, the king's knight, and then the king's bishop. The Italian opening follows the same sequence. Likewise, in many lines of the Queen's Gambit, White will deploy both knights before moving a bishop. In other lines one knight comes out and one bishop a move or two later, while the other minor pieces await developments that reveal their best square.

However, in the London System, White plays the queen's bishop on the second move, and may bring out both bishops before a knight moves. Likewise, Black's first minor piece to come out in the Caro-Kann is a bishop.

Erik Kislik states that knights before bishops, "is not a very useful rule" (27) in Applying Logic in Chess (2018). This rule is the first of ten that Kislik quotes from the work of some unnamed grandmaster, presented as rules for beginners. He makes an important point:
Rules in chess assume 'all else is equal',but all else rarely is equal, so we need to judge ideas based on specific circumstances. Most of the time, advice given to amateurs is in the form of rules. Chess is a concrete game though, and more often than not, this advice is too stereotypical to be of much applicable value.
Kislik, Applying Logic in Chess, 26.
Kislik runs through each of the ten rules, offering his views of how each develops principles in certain circumstances but falls short in others. His analysis is almost completely verbal, with few diagrams and analysis of specific positions.

The Review

John Hartmann sold me Kislik's book through his review in Chess Life ("Logical Ambition," CL, September 2018, 20-21). Hartmann calls Kislik's book "one of the most interesting titles to appear in recent years, ... also one of the most maddening" (20). Hartmann notes that the cover, with a flowchart for making decisions in chess, is "misleading": "There is nothing in the text that resembles a flowchart for thought" (21). Kislik's view of logic and reason is more modest.

Another book on my shelf offers flowcharts, Paata Gaprindashvili, Imagination in Chess: How to Think Creatively and Avoid Foolish Mistakes (2004). I reviewed it here on Chess Skills in February 2017. The core of that book is found in the quality and difficulty of the exercises. I have found the flowcharts marginally useful.

Hartmann's comments took me back forty years when some fellow undergraduates were taking a course on logic and making the efforts to systemize thought in terms like, "if p, then q". I did not find such an approach to logic any more useful for learning to think than studying semiotics for learning to read and write. The notion that seemed to represent this more modest view of logic, which Hartmann quotes from later in Kislik's book, that chess errors always can be explained clearly, was enough to interest me in the book.

Hartmann also notes that, "there are multi-page stretches unsullied by diagrams or analysis" (21).

Kislik's Assessment

After declaring the rule "not ... useful", Kislik highlights both its merits and shortcomings. He starts out noting that the corollary to the rules that, "developing bishops early on is suboptimal ... is definitely not true" (27). What matters, he suggests, are the reasons. Kislik highlights piece coordination, the principle of improving the worst-placed piece, and flexibility. The last is where the rule's merits become evident. The knight on g1 usually finds itself well-placed on f3 early in the game, but the optimal placement of the bishops is less certain.

His views on this rule and those that follow are thought provoking and worthy of attention. Nonetheless, his discussion seems incomplete. He laments the instruction methods for beginners that proclaim these rules without, "making sense of the principle or idea, or understanding where it came from" (26). My way of thinking about "where it came from" drives me towards historical explanations. Kislik does not offer any history of these rules.

In Common Sense in Chess (1917), Emanuel Lasker offers the text of lectures that he presented in London in 1895. In the first of these lectures, he develops four rules--including knights before bishops--through concrete analysis of several short model games. Five years ago, these rules and games, as well as a few others that I selected, comprised the core of my lessons for youth players over several sessions (see Lasker's Rules).

Rule Independence

Erik Kislik is not original in his suggestion that concrete analysis of specific positions should take precedence over abstract and universal rules. This idea was well-expressed in John Watson, Secrets of Modern Chess Strategy: Advances since Nimzowitsch (1998). Even so, strong Grandmasters who teach young players still promulgate these rules with the understanding that their pupils will need to learn how and when to violate them. I recall during a tournament broadcast a few years ago, hearing Peter Svidler discuss his struggle with both promoting and resisting the teaching of such rules. These rules have a purpose even though in the long-run they can retard development.

Consider the very common position after 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5

White to move

Many youth players will not reach this position because they would have played 3.Nc3. While this move is not inherently bad, young players will make it by rote, often oblivious to the moves played by Black. They will often play it without thinking. Kislik's underlying notion, it seems to me, is that even at this early stage of the game, it is critical that reasoning must be part of every move. Whether one plays 3.Nc3, 3.Bc4, 3.Bb5, 3.d4, or some other move, it must be rooted in understanding.

From the diagram, most of the youth games that I have witnessed continue 4.Nc3. Master games, on the other hand, more often proceed with 4.d3 or 4.c3 (which violates one of Lasker's rules). In my play, I favor 4.c3 as more dynamic, and I usually will follow it with 5.d4. However, as more and more opponents fail to exhibit the greed that leads to disaster in the Greco Gambit, I am shifting towards 5.d3.

In my play and in my teaching, I teach students that it is okay to play 4.Nc3 (or 3.Nc3), even though I think there are stronger moves. What is critical, I urge is that these moves are made with thought and understanding, not simply played by rote. In the end, that's the point of these rules for development: they are guidelines that assist our thinking, not rules that direct our play. I think Kislik agrees.

Irony

If I could simply always remember everything that I once knew, my chess play would be stronger. Among the dozen or so miniatures that I regularly show to my chess students is one that I won in thirteen moves after showing up twenty minutes late for round two. From this position, I played my move, and after a few minutes thought, my opponent resigned.

Despite knowing every move in this game, I somehow failed this tactics exercise last night.

Slight Advantage?

Sometimes the variations in published analysis sends me off in pursuit of an idea. Such was the case today while reading through annotations to Akobian,V. -- Shankland,S., St. Louis 2018, one of Shankland's victories enroute to winning the US Championship (Chess Informant 136). To Akobian's ordinary looking twelfth move, placing his bishop on the diagonal to oppose Black's, Danilo Milanovic gives the evaluation ?!, suggesting instead an intermediate attack on Black's queen. There are three options offered for Black with the longest line going another ten moves to reach this position.

Black to move

Milanovic states that White has a slight advantage? Why? Control of the c-file? The bishop's greater mobility over the knight?

Surely such an ordinary looking position has occurred in countless games. This exact position cannot be found in the database, but searching for games where both sides have two rooks, there is a bishop versus knight imbalance, and 4-6 pawns each, turns up hundreds of games.

I searched the database of my online games and found many entertaining blunders in seemingly routine positions. For example, I lost this game three days ago because I was oblivious to the creation of exploitable weaknesses.

Black to move

Play continued from this position 22...Rd1+ 23.Re1 Rad8 24.Kg1 b4 25.cxb4 Bxb2 26.Kf2 Rxe1 27.Rxe1 Bc3 28.Re4 Bd4+ 29.Kf3 Bb6

White to move

Perhaps White has a slight advantage with the queenside pawn majority and a more active king. But, an active king can be a vulnerable king, too. Inexplicably, I played 30.a4??

Black wasted no time pointing out the error and I resigned four moves later.

Attack with Simple Moves

The past two days I have been going through games and analysis in Mihail Marin's column in Chess Informant 136, "Attack with Simple Moves" (47-58). The 1967 game Portisch -- Petrosian, in particular, captured my interest.

Portisch,Lajos -- Petrosian,Tigran V [D13]
Moscow 3/584, 1967

1.d4 d5 2.c4 c6 3.cxd5 cxd5 4.Nc3 Nf6 5.Nf3 Nc6 6.Bf4 e6 7.e3 Bd6 8.Bg3 0–0 9.Bd3 Re8 10.Ne5 Bxe5 11.dxe5 Nd7 12.f4

Black to move

12...Qb6

Mikhail Yudovich, who annotated the game for Informant 3, gave this move a question mark. Marin adds, "A curious 'pawn grabbing based' plan with incomplete development" (53). Curiously, the diagram position has occurred in at least 18 games (Portisch -- Petrosian was the second) and 12...Qb6 has been played in 13 of these.

In the one previous game, Max Euwe won from the Black side in 20 moves after 13.Qe2. But White has a healthy 65% score over the 13 game batch.

13.0–0 Qxe3+

Yudovich recommends 13...Nc5, which still remains unplayed in subsequent games.

14.Kh1 Qb6

After 14...a6, Black went on to win in Stobik,D. -- Hoffmann,H., Germany 1977, and also in Pira,D. -- Van Rompu,A., France 2008.

White to move

15.Qh5

15.Nb5 was played in the only other game to reach this position, and Black won, Dreyer,M. -- Mohammad,S., Yerevan 1996.

15...Nf8

Marin offers two alternatives: 15...h6 and 15...g6. My computer suggests that 15...g6 is Black's only hope for eqauality.

16.Rf3 Ng6 17.Bf2 Qd8 18.Nb5

Marin notes Black's "chronic weaknesses" (54). This position is the sort that I am always in search of to present to my students for illustrating the consequences of pieces that are mere spectators. All of White's pieces are in the battle on the kingside, or will be soon. Most of Black's pieces are doing nothing.

18...Nce7 19.Nd6 Bd7

White to move

20.Bh4

20.Nxe8 wins the exchange, but gives Black time to bring the rest of his pieces into the game. It is a grave error to exchange a strong attacking piece for a spectator.

20...Qb6 21.Rh3 h6 22.Bf6 Qxb2 23.Rf1 Nf5 24.Bxf5 1–0

Checkmate comes soon.

Anatomy of a Miniature

Miniatures (games ending in fewer than 25 moves) occur because one of the players makes a catastrophic error. This game was played with each player having three minutes for the whole game. With such a time control, errors abound.

Chess Informant 136 came out last month, but I'm still spending my study time with the previous issue.

A Warning

When I'm trying to show young players and even adults how to think about material on the chess board, I often show a Greco game that I've played in its entirety in online blitz. It, along with Paul Morphy's Opera game, illustrates that the pieces in the battle matter, while those on the board who are watching the game do not count.

There is another relatively famous game that I've played in its entirety multiple times. Alas, these games have been quick and embarrassing losses. The players of this famous game are not well known. They seem to have surnames only everywhere I've seen the game referenced.

Calculation

Some annotations in Chess Informant 129 brought home to me the level of calculation that is necessary in Grandmaster play. While running a local chess tournament last weekend, I spent some idle time reviewing an issue of Informant that I happened to have on the computer that I was using for pairings. I took this position into the skittles room for some participants to work on between rounds.

White to move

It is White's move 24, and SP Sethuraman, who won this game enroute to the Asian Championship, said that his opponent missed this tactic when playing a7-a5 three moves earlier.

Black to move

Sethuraman suggests 21...a6 22.e5 Nd5 23.Nxd5 cxd5 Qh5 "is given by the computer as equal, but I would prefer White here" (SP Sethuraman, "Through the Fire," Informant 129, 71).

After 21...a5 22.e5 Nd5 (22...Nd7 was played in the game) 23.Nxd5 cxd5, the b5 pawn is weak.

The game continued:

21...a5 22.e5 Nd7 23.Bf5 Nxe5 and we have the diagram at the top of this post, where Sethuraman played what he called a "cute little tactic" (71).

Morra Miniatures

This morning I won a short game employing the Smith-Morra Gambit. The Morra fascinates me because I lost to it in eight moves in a chess tournament twenty years ago. I also have faint recollection of struggling against it in an email game several years later. In junk chess, that is, the online blitz that I play most days, I often employ a variation of the Morra Gambit that mimics the Danish Gambit. However, in the Danish Gambit, Black cannot play e7-e6. Against the Morra, that move is quite normal.

After winning this short game this morning, I spent some time looking at other Morra games, but between masters, using the ChessBase iOS app on my iPad. That program tends to crash, but it does give me access to the ChessBase online database. The game that caught my interest is not available at 365.com, chessgames.com, or other free game collections online. However, via the winning player's name, I was able to download a PGN file of all the games from the event from FIDE's website.

Stripes,J (1968) -- Internet Opponent (1995) [B21]
Live Chess Chess.com, 21.08.2018

1.e4 c5 2.d4 cxd4 3.Bc4 Nc6 4.c3 dxc3

This move order confuses the database. It shows eight games with 5.Nxc3 and a horrid score for White, but entering 5.Nxc3 brings up nearly one thousand games. The two most popular Black replies--5...e6 and 5...d6–-both increase the number of reference games. White's score remains such that the line might be considered a poor choice in serious competition.

5.Nf3

My intention was to play an obscure Morra variant akin to the Danish Gambit.

White normally plays 5.Nxc3 e6 (5...d6)

5...e6 6.0–0 a6

I think that Black wastes time driving the bishop to a square where it will not need the queen's protection.

7.Qe2

7.Nxc3 transposes to somewhat normal Morra.

7...b5 8.Bb3 d6 9.Rd1 Qc7 10.Nxc3

Now that White has played this move, there are reference games in the database.

10...Bb7 11.Bf4 Nf6

Black is finally beginning to get the kingside developed. White is ready to attack with all of his forces and the Black king remains in the center. Already, Stockfish sees White as having the edge.

13.Nd5! As in the King's Gambit, players of the Morra Gambit should be prepared to sacrifice a piece or find another opening.

10...Be7 is the most popular.

13.Nb5!

This move appears in two prior games in the database, one between juniors in 1997 and a more recent game between class players. White lost both games. According to my chess engine, Black can draw with best play. However, an International Master failed to find the necessary defense. Those who play the Smith-Morra in serious games might find benefits from studying this game.

13...Bd7

13...axb5 14.Bxb5+ Bd7 Both ways to capture the bishop lead to equality, according to Stockfish.  Nanni,S (1709) -- Bozzao,F (1883) Arco ITA 2015 was won by Black in 28 moves.

14.Rxd7!

Although Morphy's Opera game differed in substantial ways with Rxd7 keeping most of Black's pieces pinned, there is a way this game is similar. All White's pieces are participating in the attack, while Black's forces are spectators. In this game and Morphy's Opera game, Black's king is stuck in the middle.

14.Qd3 Eissing,C -- Philipowski,R Hiddenhausen 1997 was won by Black in 30 moves.

Avoid the Torturous Draw

White to move
Analysis Position

This position could have occurred had White played 37.Be6 and Black replied fxg5+ hoping for a rook versus a rook and bishop, which should be a draw. The difference between the analysis diagram and the game is the presence of Black pawn that White's king can use as a shield to set up a mating net.

Black's difficulties become apparent after 38.Kxg5 Rb8 39.Ra7 Kf8 40.Rh7

Black to move
Analysis Position

White threatens 41.Kf6. If not for the Black pawn, 40...Rb2, 41...Rf2+ would save the game.

Instead, White played 37.Kxf5, and after 37...fxg5+ 38.Kxg5, Black was able to hold on fifty moves and claim a draw.

Black to move

Black suffered during these fifty moves, but with both players having twenty minutes left on the clock in a game 30, Black was able to spend the time needed to avoid obvious pitfalls.

Alekhine-Chatard Attack

In the past, I have struggled against the Alekhine-Chatard Attack, which only seems to get deployed against me in blitz. I have neither faced it over the board, nor in correspondence play. Nor have I spent as much time studying the books than on other variations for White against the French Defense. Consequently, I rely on my instincts and often falter.

Last night, I faced it in a blitz game against a National Master. I won!

Black to move

Black has many choices here.

Accepting the gambit has been my usual response, but I have tried all or most of the main options. I have lost more than I have won. A year or so ago, while discussing this opening with a friend who has played the French longer than I have and is higher rated, he mentioned that Black can simply castle.

Viktor Moskalenko recommends castling in The Even More Flexible French (2015).

6...0–0 7.Bd3

According to Moskalenko, 7.Qg4 is the "most aggressive option" (339). According to PowerBook 2016, however, 7.Bd3 has a better scoring percentage for White.

7...f5?!

7...c5 is the recommended move.

8.exf6

8.Nh3!

8...Nxf6 9.Nf3

Black to move

9...Nc6!?

I have two prior games from this position. Both are losses.

9...c5 is the only move in PowerBook 2016.

10.0–0

10.Qe2 was played in those two prior games. One ended quickly: 10...Ng4 11.O-O-O Nb4 12.Bxh7+ Kxh7 13.Bxe7 Qxe7 14.Ng5+ Kg8 15.Qh5 and missing 16...Bf5, I was mated two moves later.

10...Bd7 11.Qe2 Nb4

White to move

Perhaps Black has equalized. Both players have several options for the struggle. Having castled kingside, White's thematic pawn storm is less of a threat. My opponent quickly lost his way.

12.Bxf6?! Bxf6 13.Ne5? Nxd3 14.Qxd3 Bxe5 15.dxe5 Qxh4

White to move

With a one pawn advantage and no problems, I went on to win.

Quest for Advantage

This morning's blitz session ended after two games, a win and a loss. In the second game, the win, I found the only move that maintains a slight edge from this position. My opponent then failed to find a move that kept it close and his position deteriorated rapidly. He resigned three moves later.

24...e5

What should White do?

Winning Advantage?

Stockfish and other engines give White an advantage of 1.7 to 2.3 pawns, but cannot suggest an approach superior to that played in the game.

White to move

52.Rh7 Kb6 53.Kb3 Ka6 54.Rc7 Rg8 55.Ka4 Kb6 56.Rg7 Rf8 57.Rg6+

Black to move

57...Kxa7 58.Ka5 Kb7 59.Rg7+ Kb8 60.Kb6

Black to move

Black saw that he had reached a Philidor Position and easily held the draw with mere seconds remaining on the clock.

Did White have another means for securing a win that the engines might suggest if allowed to "think" longer?

Finishing

During Inland Chess Academy's Spring Break Chess Camp last week, I presented four sessions. My topics were weakness, patterns, coordination, and finishing. The following is an outline of the fourth, finishing. Click on the links for some of my previous posts that expound upon some of these techniques.

Finishing


To score well consistently in chess competition, you need to have the skill to convert an advantage into a win. Often, also, you need to hold a draw when you have a slight disadvantage.

To develop this skill, learn (in approximately this sequence):

Checkmate with heavy pieces—two rooks or rook and queen
Checkmate with one heavy piece
Winning and drawing positions and techniques when one side has a single pawn (opposition and outflanking)

Black to move
Black draws with best play
Winning techniques when one player has a pawn majority on one flank and an equal number of pawns on the other flank
Use of opposition and outflanking to secure the win or hold the draw when both sides have the same number of pawns
Some stalemate ideas when kings and pawns are all that remain
Checkmate with two bishops
Holding the draw with Philidor’s idea in rook and pawn against rook
Winning from the so-called Lucena position (building a bridge)
Queen versus advanced pawn—winning techniques and positions, drawn positions and techniques
Tactical tricks in rook endings (and the corresponding drawing ideas)
Checkmate with knight and bishop*
Queen versus rook—elementary winning positions and ideas

Of course, these skills are only a beginning, but they are a very important beginning. These skills are called fundamental because they are the foundation upon which you can build lasting skill. Without this foundation, your success in the opening and middle game will often crumble in disappointment.




*Jeremy Silman does not agree that this skill is necessary

Winning?

Does Black have a winning advantage?

Black to move

This position is from an online blitz game where White made an obvious blunder in time pressure. I am not certain that Black could have broken down White's effort to construct a fortress without the error.

Deflection

Checkmate is forced from the first position on the worksheet called Bishop Award: Checkmate and Tactics that I give to my students. The position comes from Maczuski -- Kolisch, Paris 1864. That exercise asks students to find White's fourteenth move and the idea that girds it.

The position below is before White's move 12 in the same game. The forced checkmate is not yet on the board, but White has a winning idea.
