| Polugaevsky v. Petrosian (After 19.__Rxe3) |
1. Nf3 g6 2. d4 Bg7 3. c4 d6 4. Nc3 e5
{This game ended in only 24 moves after a knight's fork against white's rook
and queen. The game, short as it may be, provides an instructive example of
attacking a weakened pawn.} 5. e4 Nc6 6. dxe5 Nxe5 7. Nd4 a6 {This pawn push
prevents white's knights from jumping to b5.} 8. Be2 c5 9. Nc2 Be6 10. Nd5 Bxd5
{Taking the knight seems the best move for black. A knight on d5 is very
dangerous and creates a wide range of threats.} 11. exd5 Ne7 12. O-O O-O {At
this stage of the game, black seems to have the advantage. The bishop on g7 and
the knight on e5 are more active compared to white's pieces.} 13. Rb1 Nf5 14.
b4 {White tries to make complications on the queenside.} 14... cxb4 15. Rxb4
Qc7 16. Bb2 Rfe8 17. Nd4 Nxd4 18. Bxd4 Nd7 19. Be3 {I think its better if white
has exchanged this bishop instead of retreating it to e3.} 19... Rxe3 {This is
a very good move from black! With this exchange sacrifice, black created a weak pawn for his attack.} 20. fxe3 Nc5 21. Qc2 Re8 {Black now focuses on the
weak pawn on e3.} 22. Rf3 Bh6 23. Qc3 Qe7 24. Rb6 {This is a blunder. But
black's position is already difficult and losing.} 24... Na4 0-1
