It seems to be a very interesting testposition. The resulting pin is awsome, but the real 'losses' occur only several moves later.

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. This line indeed seems to be OK for Black. But knowing Karpov, he will not play a risky line in such an important game, at the risk af having a 'hole' somewhere, so I still suspect there has to be an improvement. >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. The point of 25 ... Rf8 and 26 ... Qe6 is to exchange queens by means of Qb6+ or get the king away by Ke8-f7-g8. 27 e5!? is a very interesting try, I will analyse this later. Maybe this is the line Anand feared? >About 26...Kf7: While I respect Anand for playing it, seems no doubt >that this is the losing move. Qb8 of course (-0.50). Probably he missed the strenght of Karpov's Qxg7+ later on. The endgame might be better for White, but I agree Anand should have tried it. Regards, Jeroen
