It’s Your Move: daily chess puzzle # 78

Black to play and win

Vranesic v Larsen, Amsterdam 1964

Solution

A nice piece of calculation is required, but the usual examine all biffs and LPDO motifs being relevant (the LPDO being the Ra1). 1…Re5! 2 Ne5[] Bf2+!

White must take, since if 3 Kh1 Rb1+ 4 Kh1 (4 Rb1 Qb1+ 5 Bf1[] Qf1 mate) Qf1 mate. After 3 Kf2 Qd4+ wraps up. A bit of care is needed depending on where the K moves (and not falling into Qe5+ Be4 Qa1?? Qe8 mate).
