Ruderfer vs Dvoretsky (USSR Championship Semi-Final, Odessa 1972)
Black to move:
The E column it's not avaiable for the white king!Because if:
59. Ke3 (or Ke1 and even Ke2 later) then
59. ... Rxg6
Pawn and king are in the same column! The simple: 60. ... Re6+ win the game. Neither
60. Re8 work! (a rook in front of a passed pawn is not strong... and the black king will arrive there very soon...) The pawn will fall in any case! And black win.
So the white king prefer to remain in the A, B, C, D colums and take the draw for perpetual check.
In fact the checks can't be block by interposing the white bishop because the white rook is ready to be take by the black king.
