Hi Lance,
Are ther other changes in 4.5c? If not, I could replace 4.5b in my recent tournament.
Also, may I have a wish? Can't you provide a change log? It is much more enjoyable to know what happened to the engine.
BTW, my last LCT2 tests with 4.4b and 4.5b showed an improvement of 140 Elo!! Even if LCT2 is very unreliable, the improvement is huge. I am looking forward to seeing Thinker's results in SzG Swiss 3rd division.
Best regards,
Gábor
