Interesting that not a single one of the 42 games among the top half ended in a draw. Clearly Crazyhouse does not suffer from a draw problem. But do you have the White vs. Black stats, for the whole tournament and (if possible) for the 42 games among the top half? From what I've read, the White vs. Black advantage in engine play is a huge problem especially among strong engines.

You know that there are (small) ZH books available too? There was a huge ZH boom a few years ago and Ferdinand (et al) created several tournaments and also added freely available ZH start positions for download. So I think the White advantage was reduced with start positions.

Just one of the main threads in that time
http://talkchess.com/forum3/viewtopic.p ... crazyhouse

I don't know though if Carlos had used one of those books, I guess not.

Since that time the XB/UCI chronology has a ZH section too.

White 72 wins
Black 58 wins

It's at the bottom. I don't have the statistics of the top engines, but here are the games:

No this time, they played without books. I have my own suite (some positions I borrowed from Ferdinand's first book) that consists of 54 opening positions.

Was the White to Black win ratio much different between the 1e4 games and the 1.d4 games?

Yes.

1. e4 => 72.9% for white
1. d4 => 57.6% for white
