Rc3+ seems like it will hold. For example: 35.Ke2 Rc2+ followed by either 36... a2 or 36... Rxg2. Alternatively, 35.Ke4 Rc2 36.Rxa3 (36.Kd5 Rd2+) Rxg2 If 34.... Rc3+ does in fact hold, then how does White vary between 26.Kf3 and 34.Ra7 in order to win? ---------------------------- After 24.h3, the position is too complicated for me to exhaustively analyze; the lines I examined (mildly) suggest that White is winning. Two sample lines are: 24...Kf7 25.Rxd5 Rb2 26.c6 Rc2 27.Rd7+ Kf6 28.c7 (evaluation unclear to me) 24...Rb2 25.Rc1 Rb8 26.Kf2 Kf7 27.Ke2 Ke6 28.Kd3 Ke5 29.c6 Kd6 30.c7 Rc8 31.Kd4
