Thanks Uri, for correcting that! Of course it should have been 48. ..Qf6-d6. Sorry! I like seeing Tiger play 46. a5-a6 very much! It seems more natural than Qb4 or Qe2 but that is probably just because you would want to prevent Black playing a7-a6. But after the alternative 46.Qe4-b4 the reply 46. ..a7-a6 does not seem to work anyway. So the computers are playing b6-b5 and a5-a6 with other purposes in mind probably than just breaking up or defending the pawn formation. After 46.a5-a6 I get from Q5T output that it wants the king to go hide on a8 not c8, Thorsten. Does Tiger play 47.Rc2-b2? Then Q5T would play 47. Rd8-b8, evaluation +0.27 now for Black and it is probably underestimating 46.a5-a6. Very nice move from Tiger, I think! Thorsten, you did not put 46.a5-a6 in your message below?
