[MM]

My first results for Critter 1.4.

1 Houdini 2.0c Pro x64 (4c) +29 +83/=159/-58 54.17% 162.5/300
2 Critter 1.4 64-bit SSE4 (4c) -29 +58/=159/-83 45.83% 137.5/300

My result at ultra-short controls, which somehow confirms this, albeit with Houdini 1.5a. I got this several days ago, when Critter 1.4 appeared, forgot to post:

28 +/- 6 Elo points between them (95% confidence). The result is pretty reliably extrapolated to longer time controls, because Houdini 1.5 and Critter 1.4 scale similarly, in fact they are similar generally

Hello Kai, i suggest you, if you have time and will, to try with a longer increment (eg 1s or 0.5s) because Critter has problems in dramatic time trouble (under 0.9 seconds remaining).
