I rerun the test with 3 minutes. I find mostly the same.

All the others agree in the first move and the score, however Yace needs often
more time.
Additionally:
r4rk1/1bq2ppp/p1p1p3/2b1P1B1/3p2Q1/3B4/PPP2PPP/R3R1K1 w - - bm Bxh7+; id
"ECM.1597";

{381}
The "H" at the end of the moves means, that the moves were picked from the hash
table at display time, and can be different than at search time. Here, they look
correct.
From you posts, I have seen, that GLC is really good at solving mates (I mean
especially the Leonid positions, where Yace is often chanceless.) Do you have
any special trick, that you want to share? :-)
