White to move. I was playing Black.

My opponent states I could have won thru his own analysis... what do you think?

White's pawns are going up the board as you see it-- Black's king is on b3 and White's on h3-- just as point of reference.

It looks like white can win I'm not sure. Maybe with correct play black can somehow draw. I have to play this out on another board against the Chessmaster to see if it's really a draw or a win

You would need to put it through Fritz or similar. My guesstimate is that white is winning due to the poor defensive position of the black king. They only way white can be stopped is through the cooperation of the black king and rook, and here the black king is out on a limb. White can just march his pawns with king in tow, and the rook is pretty lame defending alone, as it either hits a file (whereupon the white king can advance beyond his pawns) or a rank (whereupon the white king just sits in support).

So to answer the question, I disagree with your opponents assessment that you could win. A draw as an outside bet, maybe.

Thats why computers will inherit the earth. The two early rook checks on the f-file are the key. And the reason I am not a grandmaster 🙂

Game 4421447
Win for black whoever moves.

1. h5 .. Kc4 (black must get his King across to the scene of action to win);
2. Kg4 (supporting the pawn advance and preparing to cut off blacks king) .. Kd5 (continuning to approach the pawns - note that black has plenty of moves in hand as whites pawns cannot advance too fast without blacks rook snapping them up);
3. Kf5 (hindering blacks kings intentions) .. Kd6 (heading round the King to g8 / h8);
4. Kf6 (still preventing the black king crossing the e file) .. Rf1 ( 4. ... Rg1 does not work after 5. h6 .. RXg3; 6. h7 .. Rh3; 7. Kg7 .. Re7; 8. h8=Q .. RXQ draws);
5. Kg7 .. Ke7 (once again black can approach those crutial squares);
6. h6 .. Rf7+ (the critical winning move);
7. Kg6 (7. Kg8 loses quicker .. Rf5; 8. g4 .. Rg5; 9. Kh7 .. RXP; 10. Kh8 .. Kf6 (black needs to take care about a stalemate now); 11. h7 .. Ra4; 12. Kg8 .. Rh8#) .. Rf3;
8. g4 .. Rg3;
9. g5 .. Kf8;
10. h7 .. Rh3;
11. Kf6 .. RXP and it is only a matter of time.

What is interesting is the situation if the black King was further away (say on a1) or the white King better placed (say on f5). In both those cases it seems black cannot get his King across to the g & h files quickly enough and he will have to give up the Rook for the last pawn.

If the pawns were advanced to the 5th rank and supported by the king then white could even win.

Did you analyze that on your own?

Basic ideas were mine but I used Fritz to blunder check!

but I would not have bothered to even look at this if my first impression had not been that it was a win for black.
