I played a game yesterday in which the ending illustrated quite well IMO some of
the differences between the human and computer approaches to certain positions.
The game was played in 2 minutes with a 12 second increment.
[D]8/3p1pkp/3Pp1p1/1bR1P3/p7/1r5P/2N2PPK/8 b - - 0 35
I was clearly winning but had to still convert the point and my only worry was
that he might find a way to get at the d7 pawn. My opponent had just played
35.Nc2 and was threatening 36.Nd4. This looked tough, and I admit I only saw the
problem after he played it. Chess blindness had me prepare 35...Bc6?? in my
mind. Luckily for me I found an interesting resource which I calculated to the
key 40th move. The funny thing is that no engine will play the 40th move and
they go on to their usual long sequences, which win also it's true. For this
reason, they also take quite some time giving 35...Rb2 its due credit. Once you
see the 40th move though, there is nothing to calculate. It's over. My opponent
must have missed it too or he might have tried something different.
35...Rb2 {88} 36.Nd4 {5} a3 {3} 37.Nxb5 {23} a2 {1} 38.Rc1 {49}
Rb1 {2} 39.Nc3 {4} Rxc1 {2} 40.Nxa2 {2}
[D]8/3p1pkp/3Pp1p1/4P3/8/7P/N4PPK/2r5 b - -
40...Rc4 {2} The knight is boxed in and the rook is in a dominating position. I
left the rook there and my opponent resigned a few moves later.
