Well, as usual, this is short TC, and Igel has made a very big step recently in this domain too. Don't hurry too much, let me fill the gap :D

Minic 1.42 is available.

This is a time management bug fix release for incremental TC like 2min+1sec. In this case, this is a +30Elo patch. I don't know if Minic was already tested at new CCRL blitz TC, but this can't be good, this release is fixing that.

In other cases, like 40/25, this release is not much better (so absolutely no need to stop 1.39 test currently running).

Minic 1.44 is available with probably +15Elo more.

And much better than 1.35 at sudden death TC

Code: Select all

Score of minic_1.44 vs minic_1.35: 70 - 34 - 151 [0.571]
Elo difference: 49.4 +/- 27.1, LOS: 100.0 %, DrawRatio: 59.2 %

Could you expand on what you are doing there ?

Your code source is available for a look, but an explanation of your thought process, what you tried, etc. is a useful complement to raw code.
