    After 11.Ke4 black either mates in 18 more moves with 11...Rh4+ or plays the alternative winning move 11...f5+ which means the puzzle must stop. This is not the most conclusive problem, however high rated players are likely to appreciate how dangerous the final position is for white.

    Good problem.  The inconclusiveness makes this one a very appropriate training tool.

    I got this problem right, but I wish I could take the credit away. I did not calculate the line to the end, so I was really just groping in the dark. This means that in real game I would never have played the first move, unlike the aforementioned and courageous Abhisek2.

    Uh... I have a correction to make.

    Well to be honest this is just a side variation my engine calculated after the game was finished.

    My opponent actually took the knight on g4, to be mated quickly:

    Qxe4+ Bf4 f5#

    I definitely spent time calculating though. 

    It just looked really good.

    Wow 4 people got it right, that's pretty good.

    Amazingly after 1 ambiguous move that meant the puzzle had to stop, the puzzle re-starts with every move in the diagram below being the only winning move (excluding repetition moves where the computer gives an evaluation of zero). It is the lack of a nice tactical start, the alternative repetition moves and again a not very conclusive finish that prevented me making the puzzle below into another TT problem.

    Ten moves for both sides? Even Fritz would find this one tricky. I would prefer short, difficult tactics.

    Fritz takes ~1-2 minutes for it, not as fast as other engines.

    9 out of 10 - missed the last move! A really nice puzzle.

    After kingxg4 why not f5 isn't that mate?

    @misterchocolate in the game my opponent mistakenly took on g4, I mated him pretty.

    Hmm, run of the mill mate in 28! This is the deepest sequence I have ever seen on Tactics Trainer

    mate in 28? hmm..Yeah when I played this game in online chess it was fascinating, however my opponent blundered by taking the knight on g4 and ran into engine took a long time to find the winning sequence when it analyzed it after the game.
