>I looked at this game briefly yesterday. I didn't pay much attention to >Junior's eval because I think these unable-to-castle positions are very >difficult for computers and I prefer the judgement of world-class >humans. Junior was not thinking about 22.Rc8 but I though Anand was >doing the right thing. I did look into 25.Qxe4 long enough to see that >it loses. How long does it takes Junior to dismiss this move? >Today I looked more, and I think Anand indeed missed 22...Ncxe4! It >takes a pawn, opens the c-file for a later Rc8, creates immediate >back-rank threats for white and most of all creates many threats against >the rook f5. The analysis I have is: >22... Ncxe4 23.Bf4 Rc8 25.Qb3 { 25.Qa4 Bc6 26.Qb3 transposes to the main >line. 25.Qb5+ Kf8 26.Re5 Rc5 black advantage } Bd5 26.Rxd5 Nxd5 27.Re1 >0-0 28.Qxd5+ Kh8 29.Bxe4 Rxf4 looks very good for black. I did some analysis with Rebel 9 and I think that after 22 ... Ncxe4 23 Qb5+ Kf8 24 Be3! is strong. After 24 ... Rc8 Rebel 9 gives 25 Bb3!, when 25 ... Nd6? seems to fail because of 26 Rxf6+! Qxf6 27 Bc5 with a lot of trouble. I don't trust 22 ... Ncxe4, because Black is unable to get his rook from h8 into play and given time, White continues Raf1, Bd4 crushing through at f6. Therefore I think Anand's 22 ... Rc8 might be best. >I don't see the point of 25...Rf8 26.Re1 Qe6. This may be an issue of >evaluation. Junior non-chalantly plays 27.a4 and evaluates it +0.7 for >white. At one point it jumps up with 27.e5 but then abandons it. This is >a breathtaking line: 27.e5!? Qxf5 28.exf6+ Kf7 29.Re7+ Kg6 30.Rxg7+ Kh5 >31.h3. Who wins now ? I have no idea. Actually Black wins in this line. Rebel 9 also likes 27 e5, but in the final position after 31 h3 Black wins after 31 ... Qf2+ 32 Kh1 Qf1+ 33 Kh2 Ne5. So 27 e5 is probably bad, but I like Junior's 27 a4. F.e.: A) 27 ... Kf7 28 Bxf6 gxf6 29 Rd1 Rd8 30 b4! appears to be good for White B) 27 ... Qb6+ 28 Qxb6 Nxb6 29 a5 also seems to favour White C) 27 ... g6!? (Rebel 9's choice) 28 Rff1 Qe5 stopping e4-e5 with a very obscure position. Who can add more analysis!?
