Today’s 5-second tactics
Leningrad,1936. Position after White’s 23rd move (23.Ke3) Black has sacrificed an entire Rook to try to attack the White monarch, who–with his last move–seems to be slipping away. But it is a cardinal principle in chess that a wandering King should stay away from the centre…
BLACK TO PLAY: MATE IN 5 MOVES!
Leningrad 1963. Ussr Championship. Position after White’s 29th move. Black has a clearly dominating position and his Knight on d3 ties down the White pieces. The problem facing Black is how to support his Knight and break into the White camp. Bronstein came up with a clever solution…
HOW CAN BLACK WIN?
gm Trifunovic, P
Saltsjobaden Interzonal , 1948 Position after 18 moves of play. Black had just played 18…h6, politely asking the Knight to go away. White has a clear plus: more development, active pieces and harmoniously placed, too. Meanwhile, Black still has not got all of his pieces out of the box on the Queenside. Surely White need not be so polite here…
WHITE TO PLAY AND WIN!
Moscow 1950. Ussr Ch. Position after 21 moves of play. The game has not gone well for the Black pieces, despite being an exchange to the good. The strong White Bishops pose great danger to the exposed Black King. The question is how to exploit this.
