Match 1, Game 16
When a knight occupies an impregnable position on a weak square in the centre or in the opponent's camp, it becomes particularly strong.In "That Pin of f7," I commented on game 15 of the first match between Alexander McDonnell (1798-1835) and Louis-Charles Mahé de La Bourdonnais (1795-1840). There was no world championship in their day, but their matches had qualities that would be shared by those which followed. Throughout the matches, both players refined their opening repertoire while continuing to contest similar positions.

I am working through all of the games of these two players without employing my chess analysis engines. My series of posts on this match begins with "Three Fighting Draws". Each post in the series contains links to the prior and next games..
McDonnell contested many games against La Bourdonnais's French Defense. Although the first Black move was 1...c5, 2...e6 followed. The character of the game quickly developed into an Advance Variation French in which White pursues a faulty approach. Instead of squeezing the Black position, Black's counter-attack on the weak d4 pawn gave him the initiative.

1.e4 c5 2.f4 e6 3.Nf3 Nc6 4.c3 d5 5.e5 f6 6.Na3 Nh6 7.Nc2 Qb6
7...Nf7 was played in game 9, and also in Glek -- Schenderowitsch, Gladenbach 2013. That game continued 8.d4 Qb6 9.Bd3 cxd4 10.cxd4 Nb4 11.Nxb4 Bxb4+ 12.Bd2 Bd7 13.Bxb4 Qxb4+ 14.Qd2 Qxd2+ 15.Kxd2 0–0 and White won in 94 moves.
7...fxe5 appears in four expert/master games since 2009.
8...cxd4 was played in game 13, and will be played again in the second match. One other game in the database contains this position: 9.Ncxd4 (McDonnell played 9.cxd4 ) 9...fxe5 10.fxe5 Nf7 11.Bb5 Bc5 12.b4 Bxd4 13.Bxc6+ Qxc6 14.Qxd4 0–0 15.0–0 Bd7 and Black won in 41 moves Komliakov,V (2463) -- Yagupov,I (2482) Moscow 2000.
This move was played in game 14 and the present one. It is an error in my opinion.
9...cxd4 10.cxd4 Bb4+ 11.Kf2 0–0 12.Kg3 fxe5 13.fxe5
Black to move
Deviating from game 14 where 13...Be8 was played.
14.b3 might have been worth considering 14...Rxf3+ 15.gxf3 Nxd4 16.Bb2 Ndf5+ 17.Nxf5 Nxf5+ 18.Kh3 (18.Kg2 Ne3+) 18...Qd8. White has some problems.
La Bourdonnais immediately sacrifices the exchange to win the d-pawn, rather than his slower approach in game 14. He could have made this sacrifice the previous move, however. Was he waiting for White's h2-h4?

Threatening the pawn on f3
Black improves his piece coordination, preparing a knight outpost on f5
White's light-square bishop is defending f5.

The backwards pawn is a target.
White to move
21.Rf2 Nf5 22.Nxf5 Bxf2 23.Ne7+ Kh8 Black has regained the sacrificed material with interest.
In the French defense and some Sicilians, f5 is the knight's happy square. In this position, Black controls 2/3 of the the chessboard and all of his pieces are participating in the assault. White's a1 rook remains a spectator.
22.Kh2 Neg3 23.Rf3 Ne4
Both Black knights have excellent outposts.
The queen redeploys towards the kingside where she will exert enormous pressure.
White to move
McDonnell decides to shore up the third rank for defense.
I could not find an improvement for White. 25.Be3 Bxe3 (25...Nxe3 26.Nxe3 Qh5 27.Ng2) 26.Nxe3 Qh5 (26...Nxe3 27.Rxe3) 27.Nxf5 Rxf5 28.Qh3.
Black's bishop, too, takes up an outpost. Black's minor pieces dominate the position.
26.Rb1 Qh5 27.Rbb3
Bringing his least active piece into action.
Is this rook struggling to find his role in the battle? Has each move made credible threats?
The rook penetrates and pins a knight.
White to move
Alternatives do not improve White's prospects.

The eternal knight exchanges itself for a cleric.

In the next game, McDonnell will falter once again with Black against the Queen's Gambit (see "Mating Attack").
