PART II:
It's time to get back to our 15. Bc4!? - which I think is well met by:
15... d5!
16. Bxc7! (16. Bb3 Ba3+ 17. Kb1 Be7 18. Kb2 Ba3+ would be cowardly)
16... O-O! (Toppy is right)
17. Bxa5 Nxa5
18. Ne5 ... (18. Bxd5?? Nc4+ 19. Bxc4 Qa3+ 20.Kb1 Ra8 and sign it 0-1)
18... Ba3+
19. Kb1 Nxc4
20. Nxc4 dxc4
21. Qd7 b5
---22. Rd5? ... this was the amateur game (Berbatov-Lambert 2008) but I think it is not best thanks to:
22. ... b4!
23. Qb5 bxc3 (23...Rb8 will probably just transpose)
24. Qa5 Rb8+
25. Ka2 Qb7! now Black might just be winning after this shot...
26. Rb5 Qxb5
27. Qxb5 Rxb5
28. Kxa3 Rb2 (and white is effectively a king down in this ending.)
And so I recommend that white try the novelty:
---
22.Rhe1!? ... A simple developing and centralizing move that dares Black to take a pawn.
22. ... b4!? probably the best.
(Black should probably avoid
22...Qxg2?! since
23. Qa7! b4 white can double the rooks and his play continues, while the black bishop is out of play (and the black queenside action is frozen). Alternatively, White can rush his kingside pawns up to try and denude the Black king and go for the throat.
Either way, White has all the play here, with active pieces and multiple ways to play for the win. I would hate this position as Black.
23. Qd5! Qb8
24. Re5 bxc3+
25. Qb5 Qa8
26. Qa5! ... (26. Qxc4 Bb2 27. Qa2 Qxg2 is unclear, but I think allows black too much play)
And now Black might try something like:
26. ... Qb8+?
27. Rb5 Qe8
28. Rb7 Qe2
29. Rd8 ... but now white is really much better.
So, I prefer:
26. ... Rb8+
27. Ka2 Bf8! ("A man's got to know his limitations" - GM Dirty Harry)
28. Qxa8 Rxa8+
29. Kb1 Rb8+
30. Ka1 Ra8+
31. Kb1 Rb8+ and shake hands.
Another, simpler, try is:
---
22. Qd5!? Qa5 (...Qa6!? might be better)
23. Rhe1 Ra8
24. Qc6 Bf8
25. Kc1 Ra6
26. Qc8 Ra8 With a probable repetition of moves.
Still I don't think ...Bxa2 is Black's best try in the original position; not to mention its a bit antithetical to the Russian Defense.
However, I am absolutely
certain that 22.Rd5? is a mistake.
As White I'd prefer either 22.Rhe1 or 22.Qd5.
But, personally, I would avoid all this with either
14.Rb1 or
15.Rb1. Perhaps deviate even
earlier with
9.Bd3 and avoid the mess after ...Bxa2.
Anyway, I'm
sure there's room to improve this analysis (it goes up to move 30 afterall), but I thought I'd share my findings today with other chess enthusiasts. I really enjoyed analyzing the lines after 12.Ra1 since Black has many interesting attacking ideas. Its good fun, but from a theoretical standpoint, I'm afraid it just doesn't matter.
Alas!
