ToTheDeath: Great game by Fischer- marvelous in its simplicity.
<11...Be7?!> Very passive. I believe Black should seriously consider 11...e5- gaining space, preventing the fracturing of his pawn structure with e5 and blunting the bishop on b2.
<14. Nd5 was a big mistake!! >
No, Black threatened ...f6, keeping his pawn. This is the only way for White to keep the advantage.
<18.c4!> is a star move, Black's pawns keep getting weaker. Black can't avoid an isolated d pawn on an open file because of 18...dxc4? 19.Rad1 Qc7 20.Qxc4 with a huge advantage.
<21.Rd4!> Discouraging counterplay with ...a4 (even though Black wrongly plays it anyway) and blockading the victi... I mean pawn on d5.
<24.Re3!> Whoops! Now either the a pawn or the d pawn is dropping off by force.
After this it's pretty much all over.
<34.R4d6!!> This mops up nicely- 34.Rxf7+ Qxf7 35.Rd7 Rb7! would be more problematic, with (slim) chances for Black to hold.
But after 34.R4d6!! Rg8 (forced due to threat of 35. Qxg6+) 35.Rf6! Rg7 36.b5 Black is helpless.
Not a lot of fireworks in this game, just a beautiful positional rout.
