At the end, some results of Yace. Befor, a few comments.

Ne2 seems to be another good move. In the table below, this is not found, but
after trying again, Nd5 was found after exactly 3 minutes. For Ne2 the score was
already +3.5, which probably is enough to win. But I did not check carefuly.

This should be "bm Rxc6"
>r5r1/n1q1p2k/3pPpp1/P1pP4/2P4N/R1B5/2Q3PP/7K w - - bm Bd2; id "BBC958"
Yace finds Bd2 fast with score mate in 10, then switches to Be1 with score mate
in 9. In the automatically generated table below, it is considered unsolved.
Yace, P4 2.53, 300M hash, 3 min test time. Not surprisingly, it solved less
positions than the programs you tested (especially when considering the hardware
difference). From the positions it found, for quite a few, it was rather fast
compared to the others. Some positions seem to be at the edge of finding. It
sees compensation for a sac, but just a bit too little compensation.
