I have a couple of these sacs in my test suite:

but this one is harder. Arasan does not find it even after 10 minutes on a Q6600.

This position seems to be tough for the engines I have.

If your engine finds the solution it should show at least an eval of 3+.

[d]1qrrbbk1/1p1nnppp/p3p3/4P3/2P5/1PN1N3/PB2Q1PP/1B2RR1K w - - 0 21

After a long search, Stockfish-1.6.3 likes Ne4, with a score of +3.15. The PV is below. (It appears to lead to a forced mate.) Perhaps this is part of the reason the position is difficult.

I'm curious what engines say about this:
