Re: Bad Bishop win

My hunch tells me that by removing that "bad bishop" penalty in eval function of SF10, it won't lower its strength since there is already mobility code which would detect that bad bishop. Hence, I think that is redundant. Ok, I haven't done my own compile and tests, but considering the brutal fast s...

Re: Bad Bishop win

I just checked with SF10 source just now and there was indeed a bad bishop penalty, the reason why black allowed those pawns to reach h6 for white is because it is bad according to stockfish. Eval terms are expensive during search, if (Pt == BISHOP) { // Penalty according to number of pawns on the s...

Re: Bad Bishop win

This is a weird win by Lc0 when it had bad bishop against SF10. Two pawns were also given up by Lc0 for some tiny compensation that's uncrompehensible to mere mortals.

Re: interesting game

Thanks for the game. I really liked the move 15... d3 Throwing a wrench on an already messy position. Looks like that move is only for NN-type engines. Showing 0.00 for 15...d3 according to AB engines and inferior for them compared to 15...Nf4, at least on my hardware. edit: sorry, i loaded critter ...

Re: T40.T8.610 net for TCEC15 SuFi

The developers of Lc0 and their helpers decided during TCEC 15 Super Final Leela uses the net T40.T8.610 https://groups.google.com/forum/#!topic/lczero/y6KjgY2KdE4 I made some test on my dual GPU machine with this net and with the older net 42176. The net 42176 was earlier the best against Stockfis...

Re: Test Position bm Rxc3

because I was using my weak smartphone earlier to check those lines, after 36.Nf1 the direct Bxf1 looks incorrect, that's why I traced your PC output just now but the Nb6 (Sb6) on your first post looks not top move of engines, it was only 6th. (35. Qa1 Na4 36. Nf1 Qe4 37. Rf2 Bxf1 38. Rexf1 Rb3 39....

Re: Test Position bm Rxc3

Why not show this complete win then, Mike? Or, even better, refute the output- line from my previous post, continuing just from the moves you had given before in your .pgn and now again up to 38...Rb3 ( rn1qkbnr/ppp2ppp/8/3p1b2/3P4/5N2/PP2PPPP/RNBQKB1R w KQkq - 0 1 1.
