KEG: Post II
11... Qa6?
After this, Black's game collapses. Rabinovitch would have had somewhat the better chances after 11...Qd5, e.g., 12. c3 f5 13. Nf6 [better than 13. Nd6+ BxN 14. c4 Qc5) gxN 14. cxB fxB 15. Nxg5 0-0-0 16. NxB Rde8 17. Nf4 Qd6. Now, after the text, Romanovsky took charge and gave Rabinovitch now real chances to recover. 12. Nxd4 0-0
The only way to avoid immediate catastrophe.
13. NxB fxN
Black would be sunk after 13...BxR 14. NxN Bxf2+ 15. NxB RxN leaving Black a piece down. 14. c3

Romanovsky knew what to do here:
15. b4

Rabinovitch now went desperado, and made matters even worse for himself: 15... Rf5?
If Rabinovitch wanted to play on, he had to try 15...Qc4 or maybe try wild (but ultimately losing) 15...Nxb4 16. bxN Bxb4 leaving Black two pawns for the list piece and a tad of counterplay. Now, White had a simple path to finish off the game: 16. Qb3 Ne5

This didn't blow the win, but 17. Be7 or 17. Be3 were simpler. The text allowed Rabinovitch to pull a neat trick that messed up Romanovsky's hair a bit: 17... Nf3+!
18. gxN Rxb5

This targeting of the c-Pawn was a fatal miscalculation. Rabinovitch might have made White's task harder with 19...Rd5 or 19...Rf8. 20. Rb1
20. c4 was also a winner for White. The text, however, was probably even better. 20... Bxc3?
20...Rd5 was the only prayer left for Black. After Rabinovitch's actual 20...Bxc3, Black was doomed:  click for larger view |
