    Nice puzzle. I like the part where the 'wrong' N is on e3, forcing a further slew of checks just to substitute the other one.

    Of course ... who wants to type 30 moves out by hand?

    Great puzzle. Rather worryingly, I could see no forced line but assumed black to play and wondered why it would take 30 moves.

    I think white is a checkaholic.

    To be honest I don't understand anything of this Knights tangle, very nice you solved it.

    http://www.rebel.nl/rebel10c.htm

    "Fixed Rebel 9.0's display bug in cases when a very deep mate combination is found. Rebel10 now will show now the correct mate line, see the following example:

    00:00:00 2.01 Mate in 30 moves Ne3-g4+ Ke5-f5 Ng4-h6+ Kf5-e5 Nh6-f7+ Ke5-f5

    Please note that the complete mate is found in less than one second!"

    (Last update March 26, 1999)

    A lot more commercial talk like "In other words Rebel (using anti-GM) does not need to know the sacrifice is 100% correct for this position, Rebel smells the chance of an attack and goes for it!"

    We're ten years further, have engines been messed up in the meantime?

    I had a vague idea that the solution involved removing enough defensive pieces [with check] to pave the way for an eventual mate.

    However, I solved by just looking for lines that made some kind of progress. Obviously, white must continually check, so there's few alternatives. There's no need for a complete understanding of the position up-front.

    Rebel was believed to be the most human-like engine that has ever reached GM strength. I think Rybka 3 Human has surpassed it in this aspect.

    There is no statement about who goes first. It changes things a bit, just a teeny, if it's black to move and mate.
