How did you get on with the two positions we posted on Monday?

Both were samples from Mark Dvoretsky’s Chess Tests which has just been made available as a Chessable course.

The best continuations were overlooked by a brace of World Champions. Did you spot what they missed?

Opposite Direction

Dvoretsky Missed Tactic

Lifetime Rerpertoire: The Caro-Kann

Bobby Fischer – Miroslav Filip

Candidates Tournament, Curacao, 1962

Fischer played 28 Qa1 and won after a long struggle (1-0, 66).

Over to Dvoretsky to find out what Fischer missed.

‘By playing 28 Qa1?, Robert Fischer logically continued his plan of invading the queenside with his queen. Meanwhile, his opponent’s last erroneous move [27 …Kg8-f8] allowed gaining [a] decisive advantage immediately through a queen sortie in the opposite direction.’

28 Qh5!

‘The h7 pawn is under attack, and it is impossible to defend it with 28 …Kg8 because of…

29 Qxg6! hg 30 Ne7+ and 31 Nxc6.’

It is very interesting that Fischer’s queen move went as far away as possible from the square of the strongest move.

To Simplify Or Not…?

Moving on from the middlegame to the endgame, the next position features two famous champions of the world.

Pawn ending

Alexander Alekhine – Max Euwe

Amsterdam 1936

Alekhine is a pawn down. Can he hold the draw?

In the game he played 42 Rc1, allowing the exchange of knights. 42 …Nxg5 47 hxg5 and Euwe won on move 60.

Incidentally, Euwe shared first place with Reuben Fine and Alekhine finished third, half a point behind the winners.

Dvoretsky gives this line.

‘White draws by trading off all the pieces: 42 Nxe4! Rxe4 43 Rxe4! de 44 Kg4 Kh7 45 Kf4 Kg6 46 Kxe4 Kh5 47 Kf5! c5 48 b3 a6 49 a3!

Slight variations are given and the chess engines aren’t immediately impressed but the final position from Dvoretsky’s analysis looks clearer.

King and pawn ending

It is worth going through the possibilities from here to understand how White can guarantee a draw.

Dvoretsky also provides additional analysis of the rook ending, with significant input from Reuben Fine.
