a5!! bxa kxa5 kc7 then ka6
JC
I was surprised that it seems to be so easy.
I agree with JC. 1. a5 (I wouldn’t give that move two exclamation marks) wins.
If black allows 2. a6 the endgame is easy won (black can’t defend the pawn b6).
So 1. -, bxa5+ is forced and after 2. Kxa5 white will enter one of the key squares a7 or b6.
Hmmmm.
Another opposition problem.
1. a5
The only winning move.
1. … bxa5+
Better than allowing the pawn to anchor on a6.
2. Kxa5
Black now has to prevent White’s king from finding a7 or c7, but cannot do it.
2. … Kc7
3. Ka6 Kb8 (or else allowing 4. Ka7 and the pawn is in)
4. Kb6
Opposition and the Black king must give way.
4. … Kc8
5. Ka7 etc.
Interestingly, I can’t find the win for White if the a4 pawn starts on a3 instead of on a4. It’s another one-step-ahead (or -behind) problem, similar to the one posted yesterday (“More King and Pawn endgame”).
How can I force Black to get into this position from the start of the game??
“Interestingly, I can’t find the win for White if the a4 pawn starts on a3 instead of on a4.”
You mean: “Interestingly, Fritz can’t find the win for White if the a4 pawn starts on a3 instead of on a4.”, right??
“How can I force Black to get into this position from the start of the game??”
Blackmail?
Heh.
Dear anonymous @ 7:05 (if that is your real name):
“You mean: “Interestingly, Fritz can’t find the win for White if the a4 pawn starts on a3 instead of on a4.”, right??”
Strange comment. What would be the point of people posting on behalf of Fritz? This blog, and the puzzles offered, are for our instruction in chess, not in operating Fritz. I don’t own Fritz – never have – and certainly would not need Fritz for this.
Do you?
