Carlsen-Svidler 2010 Blitz. Black to move. Can he draw by perpetual checks? In the actual game, he resigned two moves later.

Perpetual check is out of the question (after Ra5+ Be5 the only check is Rxe5+ but that loses quickly) but this endgame has some other drawing techniques: stalemate and exchanging rooks. However, according to endgame databases Black is losing (their rook) in 13 moves and will be mated shortly after. It is very reminiscent of the Philidor position, especially after the 2nd move by White listed there. The white pieces dominate the Black rook and it is soon out of tricks.

What about Ra5+ 2.Be5 Ra6 Now if bishop moves he can check again, and also if king moves. If 3.Ra1 then Ra4 Jan 18, 2022 at 17:07

13. Rg3; you can perform the moves in the endgame database I linked to, and it will tell you the best moves for White.– Glorfindel ♦Jan 18, 2022 at 17:09
