mrfery 20-Mar-15, 04:43 » Report abuse	Hard and very smart. Sending the queen to the upper corner to move eventually like an arc to h file and deliver mate in most of the cases is not obvious. Another difficulty comes from the fact that g2-g1=B must be dealt with carefully to avoid stalemate. Very very nice problem and probably the solve rate would drop to 10% or so. Thumbs up. 4.5 stars fully deserving its first price
kjesper 20-Mar-15, 07:25 » Report abuse	But what is wrong with Qa5? Since Qa5 can also bring the queen in the second move to d8, what is wrong with Qa5?
burkhard 20-Mar-15, 08:16 » Report abuse	@kjesper What about g1=N?
sirissac 20-Mar-15, 08:20 » Report abuse	This was a great problem, thanks charleshiggie. kjesper, After 1.Qa5 g1=N White has no way to mate in 3.
mrfery 20-Mar-15, 08:57 » Report abuse	@burkhard Qa8.... g1=N e2-e3. Ne2 NcxN#
chesswizzer12 20-Mar-15, 10:18 » Report abuse	They are the moves you would least expect
macheide 20-Mar-15, 11:44 » Report abuse	A great puzzle. Five stars. Thanks.
pyro_maniac 20-Mar-15, 18:00 » Report abuse	5 stars But how could the king get all the way down there with the pawn knight and bishop + rook and still leaving that own structure intact
burkhard 21-Mar-15, 01:43 » Report abuse	@mrfery I know that it works with Qa8, but with Qa5 it does not. It was the answer to kjesper question
kjesper 21-Mar-15, 06:51 » Report abuse	@burkhard and @sirissac Thanks for pointing that out, I didn't see it
coravin 08-May-23, 00:34 » Report abuse	Interesting I also wondered why Nb3 does not work if followed by Nd2 and then Ne4#? I can only think that it is because g1=B is a stalemate?
snailmate 08-May-23, 11:21 » Report abuse	@coravin I think the problem is that White has to deal with the possibility of the black bishop moving and leaving a flight square for the king.
