21.Ke3!
White's bishop has stayed at home, but not the king. His journey to the third rank gets him out of the way of the rook on h2 so that c2 is defended again – Black threatened 21...Nxd4 and then 22...Rxc2+. Observe the bizarre, yet appropriate arrangement of White's kingside pieces: the rook on h2, the king on e3, the bishop back on f1. There is an inner logic that governs a chess position. Most of the time this requires that the pieces go to conventional-looking squares, but sometimes you have to embrace oddity.

26.Qh4!
Smyslov showed his willingness to accept broken kingside pawns in order to render the d6-pawn indefensible. Reshevsky tried 26...Qd7, but the d6-pawn dropped all the same after 27.Qd8+ Qxd8 28.Bxd8 Nd7 29.Bc7 Nc5 30.Rxd6 and White went on to convert the extra pawn.
