plang: Played in the first round - this was the first meeting between the two greats. 11..Nbd7 looks more logical than 11..Qc6.
Smyslov after 15 Qd3!:
"The correct way of handling the position. The exchange of queens on d3 favors White, as he gains the possibility of rook operations on the c-file. With the advantage of the two bishops and strong Q-side pressure, he can be hopeful of success in the endgame."
If 27..Rd4 Smyslov gives 28 f3 with the central pawns giving White a clear advantage.
<delterp: I see a slightly different line:
29 ...xf2 30 f3 f5 31 d6! xd6 32 xb7 and 33 xa6 queening the a pawn without much trouble. >
In this line 32..Bxh2 looks complicated. Smyslov's explanation is similar to <KingG>.
If 31..Bd8 Smslov gives 32 Bxa6..bxa 33 Rb8.
Smyslov after 34 f4:
"The white king has taken up a good post, from where it restrains the advance ..c4, and in certain variations defends the a5 pawn. White can now begin active measures on the K-side, so as to open a file for his rook."
I think Smyslov is my favorite endgame player - he makes it look so simple.
