Who can resist the lure of a stalemate trap?
We have already seen some stalemate traps in action in our series on chess tactics and today we return to the theme, this time with the emphasis firmly on the endgame phase of the game.
Dvoretsky's Endgame Manual 5th Edition
Zuger vs. Ru. Rodriguez
Dubai Olympiad, 1986
White to play
This just looks lost for White. His c-pawn cannot be saved and Black’s pawn majority on the kingside would appear to constitute a winning advantage.
The first part of White’s remarkable drawing plan is to use the c-pawn as a decoy.
Black’s king had to react to the advance of the pawn but this gives the white king scope to encroach upon the black pawns.
Attacking the f-pawn. Capturing the pawn cleanly would bring a winning advantage for White, so again Black has to react.
According to Nunn: ‘The best chance, as 3…gxf4 4.Kxf4 Kd6 5.Kf5 Kd5 is an easy draw.’
What should White do now?
Nunn shows how 4.f5? g3 5.f6 Kd7! allows Black to prevent the f-pawn’s progress while still being able to promote the g-pawn.
What Would You Play?
Now there is only one good move for White. What would you do?
There is an explanation as to why 5.f5? and 5.Kd4? both lose in the course and some independent analysis would prove to be a good exercise too.
The next few king moves represent best play by both sides.
Springing the Stalemate Trap
It looks like the black king has outmanoeuvred his rival. The f4-pawn cannot be defended any longer. Is White now going to resign?
No! The truth of the situation suddenly becomes clear. If Black captures his prize with 8…Kxf4 then White will be in stalemate. If Black declines the booty with any other moves then White plays 9.Kxg4, protecting the f-pawn at the same, with a winning position.
A draw was agreed at this point.
A Stalemate Echo From Another Era
The final twist is reminiscent of a famous ending featuring two challengers for the World Chess Championship.
Mikhail Chigorin – Siegbert Tarrasch
White to play
Chigorin, who was not at his best at this tournament, played 50.gxf6?
52.Kh3 Kf4 and White resigned; 0-1. Black will win both the remaining white pawns and then promote at least one of his won.
However, Chigorin could have saved the position, as unlikely as that may seem.
50.Kg4! is the way to do it.
At first glance, this appears to be little better than the move played in the game – but there is a hidden twist coming.
Now 51…hxg6 52.fxg6 leads to a draw. Both sides will promote a pawn in the main line. More homework for you, dear readers!
The most interesting move is 51…h6.
It looks like White will be forced into a position where his king will have to abandon the defense of his pawns but that turns out to be part of the miracle ‘save.’
Another Stalemate Trap
White to play and draw
Extraordinary! 52…Kxf5 leaves White stalemated, as does 52…Kf4.
Position after 52…Kxf5
Anything else would allow the white king to oscillate between g4 and h5, with the stalemate trap hanging over the position in permanent fashion.
