Hi, Kai!

Can I have the dataset, too? The last one (Draw 5-men) I got from you uncovered some search issues for which I've never thanked you

I'm actually testing endgame bitbases for Zurichess [1]. So far after adding KPK, KRK, KQK and KRKR I've seen 0 Elo improvement. I'd like to see if egtb make sense for positions closer to the endgame.

[1] https://bitbucket.org/zurichess/endgame/src is the current generator. Not very fast, at ~2 secs for a 3-men table.
