This is the only position that dark thought failed to solve after an hour with
alpha 600Mhz

chessmaster 6000 with ss=10 solved this position after 2 hours 22 minutes and 52
seconds on pentium200MMX with 128 MB hash tables.

The previous line of chessmaster6000 was identical to hiarcs7.

I think that Nxe4 leads to better endgame for white when g5 leads to equality.
