One additional note. Alena is correct (as usual). I had originally spotted 1) Nd5, but then thought I had “cooked” it with Nxd5, completely overlooking 2) Qh7+, Bg7 and 3) Qxg7# (in case anyone else also missed it). I actually thought 1) d5 looked very strong instead, but while it wins some material, White is already two pieces behind and would certainly not get a winning position when the dust settled. Congrats again to Alena!
5k2/4nP2/7r/8/2B5/5R2/K1p1pR2/8 w Ryabinin 1999 One of the toughest puzzles I have given you.
8/3k4/1K6/8/4BR2/4p3/4p3/8 w Reti and Rinck
2R5/8/2P5/6Q1/2k5/p7/2K5/8 w Hoeg Niels Find the shortest mate.
8/8/8/8/3k4/5K2/2pr2P1/2R5 b Black to move and win.
1. Nd5+ exd5
2. Bxf6+ Kd6
3. Be5+ Ke7
4. Bd6#
