Tremendous oppertunity - Mikhail Botvinnik vs Milan Vidmar (Nottingham 1936)
Opening: D60 (Queen's Gambit Declined: Orthodox Defense. Botvinnik Variation)
1. c4 { Notes by Alekhine } 1... e6 2. Nf3 d5 3. d4 Nf6 4. Nc3 Be7 5. Bg5 O-O 6. e3 Nbd7 7. Bd3 { The variations starting with 7
Rc1 have been so much analysed of recent years that the
text-move, though it allows the immediate ...c5, offers better
fighting chances. } 7... c5 8. O-O cxd4 { As the Black pieces are not
developed so as to attack the isolated d-pawn, the better
policy here is the usual line 8...dxc4 9 Bxc4 a6 10 a4 Re8. } 9. exd4 dxc4 10. Bxc4 Nb6 11. Bb3 Bd7 { The beginning of a
risky plan, in view of White's prospects of a K side
attack. The half-pinning of his king's knight, which seems so
harmless at the moment, will in a few moves become extremely
disagreeable for Black. It was wiser therefore to clear the
situation at once by 11...Nfd5 without much danger in the near
future. } 12. Qd3 { ! Intending, if 12...Nfd5; 13 Bc2. } 12... Nbd5 13. Ne5 Bc6 14. Rad1 Nb4 { ? A second mistake, after which
White's attack becomes tremendously strong. A lesser evil was
...Rc8 in order to answer 15 Qh3 with ...Nxc3 16 bxc3 Be4. } 15. Qh3 Bd5 { This does not solve the problem of the defence,
as White preserves his powerful king's bishop. } 16. Nxd5 Nbxd5 17. f4 { ! } 17... Rc8 { Or ...g6 18 Bh6 Re8 19 g4, etc. } 18. f5 exf5 19. Rxf5 Qd6 { ? Losing immediately. The only move was ...Rc7,
after which White would increase his pressure against f7 by 20
Rdf1 followed eventually by Qh4 with decisive advantage. } 20. Nxf7 { ! Simple and neat. Black cannot avoid serious
material loss. } 20... Rxf7 21. Bxf6 Bxf6 22. Rxd5 { Much stronger
than 22 Bxd5. } 22... Qc6 { Or 22...Bxd4+ 23 Kh1. } 23. Rd6 Qe8 24. Rd7 1-0
