kxe1 is key. At that point, the only moves black can make are to shuffle the queen between a1 and a2. March your pawn up to h8, promote to a knight, and then take the pawn on c4, follows by the rook on b3 when the queen is on a1 for mate.

That was a pretty easy problem, wasn't it? I started with it for the visual impression, though. The thing that might trip up some solvers is that you have to promote the pawn to a knight.

a lot of variations, but I think

1 Rh7 wins

If ... Rxe7
2 g7, Re8
3Rh8 and black has to give up the rook to stop the pawn from queening.

If Kf6, again g7 with similar results.

Here's a puzzle of my own, an oldie but fun. White to play and win

>>47461305
Correct. I looked at >>47460425 for a while and came up with the incorrect guess of moving the rook down the file to somewhere like F1 and moving it behind the knight's pawn.

Kb7
If Rb5+ then Kc8
Now tell me why I'm wrong.

>>47461655
if Kb7, black just plays Rc5 and can draw at will by trading the rook for the pawn.

>>47461305
>>47461655
Let me try again.


c7
If Rd6+ then Kc5


Half the fun of this thread for me is using algebraic chess notation.

>>47461804
if Kc5, then Rd1. Now if you queen the pawn, Rc1+ and you lose, and if you step your king off the file, he still plays Rc1 and forces a draw.

I think I'll give up on that chess problem for now.

Here's an easy directmate problem.
