Jun-18-08		Chessical: A very rapid and impressive positional crush by Polugaevsky of a strong player's Semi-Slav Defense. Biyiasas resigns as he has no answer to the threat of <d6>, e.g.27.Bxc4 Qd6 28.Bxe5 Qxe5 29.d6+ Biyiasas seemed uncomfortable as Black in the Meran which does not appear to have been a main line defence for him. The manoeuvre <Re7> and <Ne8> seems unnatural, and I think it would have been a good idea to instead play <a5>. Did Biyiasas choose this defence as Polugaevsky had little experience with it, unlike the Kings's Indian which was a first string Queen's pawn defence for Biyiasas? It is obvious that Polugaevsky understood the opening very well anyway, perhaps he remembered G Ilivitsky vs Polugaevsky, 1953.
