According to the testers on discord, the T58 run has passed LD2 in strength. My own endgame tests put 58432 in third place behind LE and 42850. Looks like there’s more playing strength to be squeezed out of even the smaller nets.

In my test results LD2 wins. Using 2x GTX1060, I gave each net their own GPU. Time control was 5'3 No opening books were used.

Code: Select all

Engine Match

Lc0 v0.23 58432 [3] - Lc0 v0.23 LD2 [3]		22.5	-	27.5		(50: +0, =45, -5)		45.00%		Perf = -34 Elo


( 45.0% TP = -34 Elo 68%->[-80,-29] 95%->[-129,-24] 99.7%->[-184,-19] )

Btw, my 50 games are played with Hert500 by Stefan Pohl. It seems that newest T58 nets are even stronger.

Have fun! But you know, this
MoveOverhead and Slowmover Settings are only for playing on playchess. Not for tests on own Pc.

PolicyTemperature=1.520000 seems a little better.

Thanks Eduard, but on a really slow GPU (AMD Radeon card) it begins to troll as early as the middlegame (!?)
So many suboptimal moves played in a crushing positions...
