No Fritz's games were Fast (ie 30 secs/move) not Blitz (ie 15 secs/move). This is significant as Fritz's track record against Sharp2011 is about even or so in Blitz, but he dominates in it in Fast (30 secs), but this new marwin seems to have jumped in strength even at 30 secs/move.

It's true that my blitz record against bots is much worse than my fast record. That is to say, I suffer more from the speedup than an average human does.
There was a forum thread in which a two-parameter rating system was proposed: players would get a rating to reflect general playing strength and a "slope" to reflect how many rating points they gained (relatively speaking) for each doubling of thinking time. Of course it might not be linear, but the idea was to reflect in the simplest model possible that more time helps different people differently.
Indeed, iirc, 99of9 implemented this long ago when we had much less data, and found that Omar had an even steeper slope than I, whereas PMertens seemed to play just as well at blitz as at slow games. It would be interesting to re-run the model with the much larger dataset we now have.
[EDIT]
My memory was wrong. 99of9's numbers showed that I played just as well fast as slow, if not a little better. But I remembered correctly that Omar was horrible at fast games and PMertens very good at them. If anyone wants to investigate this with present-day data, this would be a good thread to bring back from the dead.

Thanks, froody. But why are there two of them?

Ok here is some data: Marwin first appeared 2008 and is written in C++. The version that competed in 2011 was 1.4MB in size, and right now he is made up of ~27k lines of code (everything included).

A more persuasive hypothesis may be that I am getting worse. I just lost nine of twelve to Sharp2011Blitz. (No, this isn't my tactic to get out of defending the Arimaa Challenge this year; I just couldn't compete.  ) |

If it had been a tactic it would be rendered invalid by your latest winning streak of 8 games against Sharp2011Blitz and marwin

Heh, I don't understand the difference. I didn't have some flash of insight to help me play better. Sometimes my brain works better than other times, for reasons unexplained.
