enoughsaid05: Opening inaccuracies of white leads to downfall.
8) d5??
White is over stretching his centre pawn without any support, with the hope of getting more space and cramming black with a gain of more tempo. However, it doesn't stay long and Tal exploits this weakness of impermanence to his fullest.
8) ...Na5!
As we shall see later, our black knight sits comfortably on the at square. The next move
9) Qd3
Attempts to protect the c4 pawn from the black knight's onslaught, but d3 is a bad place for White queen to be on.
The other option leaves white with a worse position.
9) b3?? b5!
White cannot capture in view of 10) cxb5 axb5 11)Qxb5 Bd7! And white loses his b pawn or
11) Qb4 Nxd4 12) Nxd4 Bxa1
Or white loses his rook and the important d pawn.
Back to the position at move 9.
White can't drive the knight away with b4?? in view of Bf5! and white loses his c pawn. Once he loses his c pawn, his centre collapse.
10) e4
White's attempt to fortify the centre did not go far. As we can see, 10) ...e6! leaves white in a dilemma.
If 11) dxe6, 11)...Bxe6 gives Black a good position.
If 11) other moves, 11) ...exd5 and white has to capture with cxd5. Otherwise, exd5, Bf5 and white faces the same problem of losing his c pawn again.
cxd5 leaves Tal the opportunity of b5 and continues his pawn march down the board. The game isn't in favour of White in any case. (Connected pawns are the strongest!)
The rest is all tactics.
