Last week’s puzzle: Black won by playing Rd6, threatening Qe1#. White tried Rf2 but resigned after Rd1+. As Maxim Notkin points out in New in Chess, Qf2 would have allowed the more attractive finish Bd4, again mating on e1.

I’m currently searching through my RJCC database looking for suitable puzzles for players up to about 100 strength.

This position comes from a game played in 2002 between two inexperienced players, but the same position also occurred a few years later in an Australian tournament game between a couple of fairly average club standard players. In both games White made the same mistake, but I’m sure you can do better. It’s White to move and draw. I need the next three moves in the main line.
