I just don't understand the whole deal with Garbochess, in one tournament it plays like a 2700 and in other tournaments it plays like a 2300. What's up with it?

maybe a good blitzer but not so consistent at long time controls?

Early days. I expect it to win this tournament.
However, strange things happen now and then.

This goes true also for me

Well, it takes a real hit from using 32 bit, which a lot of tournaments seem to do. Second, it's buggy . Not buggy in that it will make incorrect moves or anything, but the evaluation features did not do exactly what they were supposed to do, and there were search bugs as well. Since 2.20 I have fixed at least 15 eval. bugs, and a few search problems as well.

Finally, I only test at 1'1, so it's highly optimized for shorter time controls. Still, I'm not sure why the search strength shouldn't scale decently. That may be another bug lurking .
