Thanks, Martin. The Intel compile is about 10% faster on my Q6600.

A minor thing: displayed version is still 1.02.

Yes the version is basically the same. Except for Dann's bugfix which means a few cycles less wasted in undomove (potentially writing out of bounds but that should never happen), so absolutely no difference in strength. However the 64-bit builds should be about 30% faster (thanks to Dann again for these Unfortunately I can't test/compile the 64-bit versions myself. Thanks for feedback.

Wow that's amazing! A draw against stockfish and komodo?! against 800-1000 elo stronger opponents? I don't believe that!
I'm 100% sure it plays below 2400 (CEGT) at 1' sudden death. But recently I completed 100 games against TCB (4' 40 moves repeating) and cheng3 scored 66% so maybe it's stronger at longer tc than I expected.

Thanks Patrick

Thanks Martin, added to my collection.

It's always good to see a new original engine, especially if it comes with source

You're welcome Pablo.
