2012-01-30 19:52:48SirRick1703Nice sequence of moves and co-operation of Q and B 
2014-04-13 19:42:28chessisajedrez1746I particularly dislike problems involving a Q-K chase. This one has a reusable pattern. 
2017-08-12 21:07:19grom431789Key is Qf5+ not allowing black king to escape too early. Use dark squares to attack lone king. Nice one.
