An Unplayed Brilliancy

This was a betrayal of myself.
Mikhail Tal
There is a line of the Alekhine Defense in which the Black king strolls towards the center after White's knight sacrifice. The line resembles the Fried Liver Attack, but is more often played by Grandmasters.

In one game, Bent Larsen defended the Black side well and won a nice miniature against Mikahil Tal. In another game, Tal worked out the variations all the way to checkmate before sacrificing the knight. The Black king was driven to a1 where it was checkmated with White's few remaining pieces.

These games are fantasy variations that stem from a war of nerves in which Larsen scored an important victory against the master of attack, but still lost the Candidate's Match against the former World Champion. Tal spent fifty minutes contemplating the knight sacrifice, trusted his opponent's preparation, and opted for a safer route. He ended up in a worse position, but managed to salvage a draw in the endgame.

My interest in this line was provoked by Yasser Seirawan's excellent recent lecture at the Chess Club of Saint Louis, "A History of Chess Openings". Near the end of the lecture, Seirawan indicates that he may have mixed up the moves of Tal -- Larsen, but goes on to make some astute comments concerning opening preparation. He had spent several days been looking at "the conservative and the super sharp lines" of this opening. Tal's trapped queen and another quieter game he showed first illustrate the possible varieties. Seirawan predicts that the Alekhine Defense, like the early queen exchange in the Berlin Defense, could become a new hot trend in Grandmaster play.

Here is the game that Seirawan remembered.

Tal,Mikhail -- Larsen,Bent [B04]
Candidates Semi-Final Bled (4), 1965

1.e4 Nf6 2.e5 Nd5 3.d4 d6 4.Nf3 dxe5 5.Nxe5 Nd7

Larsen offered Tal an opportunity to drive his king to the center with a knight sacrifice.

6.Nxf7 Kxf7 7.Qh5+ Ke6 8.c4 N5f6 9.d5+ Kd6 10.Qf7 Ne5 11.Bf4 c5

White to move

12.Nc3

12.b4 is the main line in my edition of Encyclopedia of Chess Openings.

12...a6 13.0–0–0

See the next game for 13.Rd1

13...g5 14.Bg3 Bh6 15.Re1

Seirawan does not offer 15.d6, which has been played in similar positions (after 13...g6 and no 14.Bg3).

15...g4+ 16.Kb1 Bf5+ 17.Ka1 Rf8 18.Bxe5+ Kd7

White to move

Unable to rescue his queen, it is time for White to resign.

0–1

In Attack with Mikhail Tal, trans. Ken Neat (1994), Tal explains his thinking after Larsen's shocking 5...Nd7.
My intuition insistently kept telling me that the sacrifice had to be correct, but I decided to calculate everything "as far as mate", spent some 50 minutes, but then in one of the innumerable variations I found something resembling a defense, and ... rejected the sacrifice. This was a betrayal of myself, I saved the game only by a miracle after the adjournment.

Here is the variation that Tal presents in the opening section of his book.

Tal,Mikhail -- Larsen,Bent [B04]
Candidates Semi-Final Bled (4), 1965

1.e4 Nf6 2.e5 Nd5 3.d4 d6 4.Nf3 dxe5 5.Nxe5 Nd7 6.Nxf7 Kxf7 7.Qh5+ Ke6 8.c4 N5f6 9.d5+ Kd6 10.Qf7 Ne5 11.Bf4 c5 12.Nc3 a6 13.Rd1 g6 14.Bxe5+ Kxe5 15.d6 g5 16.Rd2 Bf5 17.Re2+

Black to move

17...Kd4 18.Re4+ Bxe4 19.Qe6

Black to move

Perhaps the defense that he found in his calculations was 19...Qd7, covering h3 or 19...Qb6, covering b3.

White's threat, according to Tal is 20.Ne2+ Kd3 21.Qh3+ Kc2 22.Qb3+ Kb1 23.Nc3+ Ka1 24.Bd3 Bxd3 25.Kd2+ Bb1 26.Rxb1# 0–1

Here is the game that was actually played.

Black must be better here with an active king and a pawn majority on the kingside.

All three games are instructive. This is as true of the game played as of the two unplayed fantasies.
