Test your chess: Reitstein problem 136
Black to play and win
PJS Robbertse v A Haller 1967
Solution
Black's situation looks dire, and Reitstein says that he resigned in this position. But knowing that it is a problem (and I think that is key: it would be so easy to give up here in practice) the solution is simple: 1…Qd1, pinning the LPDO rook against the LPDO Qh5, and if 2 Kf2, 2…Bg3+ wins.
White's best is 2 Qe8+, playing for tricks. 2…Re8[] 3 Re8+ Kh7?? 4 g6 mate, so 3…Kf7[] when 4 Rge3 Qg4+ scoops up the pawns, when black wins, eventually, with Q+B and more pawns v RR+B and fewer pawns.

Either the last comment is correct (Q+B v 2R should read Q+B v 2R+B), or the WB on b2 shouldn’t be there
Thank you, Stewart. I have updated the posting for your comments. Allan
