Mateo: Some instructive points in this game, both from the positional and tactical point of view:
1) 12. O-O!?, although thematic, like in some Alekhine's games for instance, is a bit surprising at first sight instead of 12.Nxd5 cxd5 13.Bd3 with a small edge for White.
2) After 16...Be8?, a very strange move, Black cannot hold. 17.d5! breaks down Lputian position. The d5 pawn is attacked 3 times, but Black cannot take it. If 17...exd5? 18.Nxd5, White wins; 17...cxd5? 18.Nxd5 Qxc2 19.Nxe7+ Kh8 20.Bxc2, White wins too.
3) The same kind of variation one move later after 17...Rd8 18.Rfe1. This time the d5 pawn is attacked 4 times, but Black loses if he takes the pawn! If 18...exd5? 19.Nxd5 Rxd5 20.Rxd5, White wins; 18...cxd5? 19.Nxd5, White wins.
4) 24...Kg7 was another strange decision. 24...Qc8 was the only way to defend the e6 pawn, which does not lose immediately although White has a huge advantage.
5) 25...b6 was necessary (but White wins anyway). After 25...Rf8 26.Nd7! wins the exchange.
Some beautiful tactical moves from Kramnik.
