Btw, this (and the previous one) is the result of a systematic check that I am doing: 15 min for each position. I started from the end of the epd file, so 400+ positions already done.

Very nice.

For the shorter mates, you may want to also limit it to a very high depth, like 200 or 240, as this may be reached before 15 mins are up.
