96MB, Fritz7.ctg, C86838-D I'm posting this game because of an interesting position that came up in the endgame. White's knight, unassisted, kept both Black's knight and King trapped helplessly in the corner, leaving White's King free to roam the board at will. If you're not interested in the whole game, just pick it up at move 28.

1.e4 c5 2.Nc3 Nc6 3.g3 g6 4.Bg2 Bg7 5.d3 d6 6.Be3 Nf6 7.h3 a6 8.Qd2 0-0 9.f4 e6 10.Nf3 Ne8 11.0-0 f5 12.Rae1 Nd4 13.Nd1 Nxf3+ 14.Bxf3 Rb8 15.exf5 exf5 16.d4 cxd4 17.Bxd4 Bd7 18.Bd5+ Kh8 19.Bxg7+ Nxg7 20.Qd4 Qf6 21.Qxf6 Rxf6 22.Re7 Bc6 23.Nc3 Bxd5 24.Nxd5 Re6 25.Re1 Rxe1+ 26.Rxe1 Re8 27.Rxe8+ Nxe8
Is this a win for White or should Black draw?

28.Kf2 Ng7?
I can understand Roger's wanting to position his knight better, but this blocks the King's escape route from the corner.

I don't see Nf6 until now, when it's too late.

Embarrassing as it is, Black should move the knight back to e8 or h5 so the King can get out. Nevertheless, it looks like the King's going to get away anyway, but...

30.Nf6+! Kh8
if 30. ... Kf7, then 31. Nxh7. But I think Roger is better off if he gives up the pawn here in order to activate his King and knight.

Black is helpless. Neither the King nor the Knight can move without ruining what's left of his position. The unassisted Knight holds them both at bay.

Black is reduced to having only pawn moves.

32.Kd5 g5 33.Kxd6 h5

34.fxg5 h4 35.gxh4 f4 36.Ke5 f3 37.Ng4
...and Black resigned a few moves later. 1-0
