It's fairly easy for humans as well. You quickly realize you don't want the Black King going to f6 and the g7 pawn is useless. You can't allow the g7 pawn to take and win and musn't take it. So 1. h7+!..Kxh7 2. Kxa7..Kg6 3. Kb6!..Kf6 4. Kc5..Ke5! 5. Kc4..Kf5 6. Kd5!! and Black is soon zugzwanged!

2...Kg6 must be followed by 3.Ka6! and not by 3.Kb6?

I think both work. I did it fast in my head and I'm pretty rusty. :(

A quick computer check...albeit likely errors says Kb6 will work.

I never bothered with the g-P moving as it only delays the win.

No, that is not right. In your variation after 3.Kb6 Kf6 4.Kc5 there is a mistake: 4...Ke5? +-, instead of 4...Kg5! =. The distant opposition leads to draw!

I see...I'll have to look at it further. It's true the King can lose a move so I may be wrong. You need to be exact to win these positions, no allowance for error.

You appear to be right but there seems it may be possible to still get the Black King fouled up. Tricky! But I agree 3. Ka6!! is the move.

Re: A pawn endgame, easy for SF hard for others

Post by Arpad Rusz » Fri Jan 13, 2012 12:31 am

I have tried to compose something... Surely not a nice position but the logic of the play is interesting:

[D]1R6/p2n2pk/qRK4P/8/4p2p/4p1N1/4P1P1/8 w - - 0 1

1. Rh8+! (Thematic try: 1. Rxa6? Nxb8+ 2. Kb7 Nxa6 3. Kxa6 hxg3 4. hxg7 Kg8! 5. Kxa7 Kxg7 6. Ka6 Kg6 7. Ka5 Kg5 =) 1... Kxh8 2. Rxa6 Nb8+ 3. Kb5(7) Nxa6 4. Kxa6 hxg3

[D]7k/p5p1/K6P/8/4p3/4p1p1/4P1P1/8 w - - 0 5

5. h7!! (This move is more surprising than in the previous endgame, the sacrifice is without check!) 5...Kxh7 6. Kxa7 Kg6 7. Ka6! Kg5 8. Ka5! Kg4 9. Kb6 Kf5 10. Kb5 Kf6 11. Kc4 Kg5 12. Kc5 Kg4 13. Kd6 Kf5 14. Kd5 +-

Can this play featured in a more natural position?

By the way, the Pawn endgame from the first post is actually the end of a prize winning study by B.Jones and R.Brieger (Benkő-75, 2003, 2nd prize).

[D]3k1Nb1/p4rp1/KN5P/8/B3p1P1/4p1p1/4P1P1/8 w - - 0 1

I have notice this about SF and think it is better than Houdini. I did a quick test for about 1 min on my system with my SF CLONE thats wasn't over clocked. As you can see SF s a beast.

Re: A pawn endgame, easy for SF hard for others

A more natural position:

A.Rusz (after B.Jones & R.Brieger)
[D]1R6/p2n2pk/B1K4P/3p4/4q3/2N1p1p1/4P1P1/8 w - - 0 1

1. Rh8+! (Thematic try: 1. Nxe4? Nxb8+ 2. Kb7 Nxa6 3. Kxa6 dxe4 4. hxg7 Kg8! 5. Kxa7 Kxg7 6. Ka6 Kg6! 7. Ka5 Kg5! =) 1... Kxh8 2. Nxe4 Nb8+ 3. Kb7 Nxa6 4.Kxa6 dxe4 5. h7!!(Paradoxally, the reason for the Rook sacrifice is not to play hxg7+; White is playing to get rid of its harmful Pawn without capturing the Black Pawn!) 5...Kxh7 6. Kxa7 Kg6 7. Ka6! Kg5 8. Ka5! and White wins by using the distant opposition.
