user31829: Carlsen-Svidler 2010 Blitz. Black to move. Can he draw by perpetual checks? In the actual game, he resigned two moves later.
[FEN "6R1/8/3B4/5K1k/r7/8/8/8 b - - 0 1"]
[StartFlipped "0"]


user7297: 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.
