Re: Hard pawn endgame

Nice long zugzwang. Current Stockfish has trouble with that. Well not that big trouble :D (and i put it by mistake just 4 GB hash so it would be faster with more) Analysis by Stockfish 021119 64 POPCNT: 1.Kf4-e3 Kd5-c4 2.Ke3-d2 a5-a4 3.Kd2-c1 Kc4-b5 4.Kc1-d1 Kb5-c4 5.Kd1-d2 g7-g6 6.Kd2-c1 Kc4-d5 7....

Re: LCZero blunders in TCEC cup 4

LC0 doesn't choose Qc6 either for my setup and the score difference is pretty big (0.76). Yes, indeed. What was odd was that my Setup didn't even look ONCE at Qc6 ! Assuming that TCEC has at least half-decent GPUs, this is quite surprising. I have tried more than 10 times with the parameters TCEC u...

Re: Fairy-Stockfish 10.3 released

OK, I made an attempt. I could not reproduce the case where Windows actually informs me through a popup that WinBoard had crashed. But when I tried to load Fairy-Stockfish 10.3, WinBoard was just hanging waiting for the engine to be loaded. It was still sensitive to a 'quit' signal, though. When I ...

Re: Fairy-Stockfish 10.3 released

2nd game went more normal even though Fairy Stockfish largeboard 10.3 was spending much more time than 10.2 but it didn't lose on time this time. I don't know if it would lose and was saved by the draw. Game was SF Fairy 10.2 8 cores versus SF Fairy 10.3 8 cores(the reverse of 1st game with the time...

Re: Fairy-Stockfish 10.3 released

I doubt that there is a problem with time management, since the time management did not change between 10.2 and 10.3. Furthermore, on variantfishtest and locally I can let it play thousands of games in dozens of variants (including capablanca) with cutechess GUI and CLI without any time losses. Tha...

Re: Fairy-Stockfish 10.3 released

...... Fairy Stockfish largeboard 10.3 works now on Winboard with HGM's modification but there is another problem now. Fairy Stockfish largeboard 10.3 lost on time in a 5'+3"(5 minutes+3 seconds/move) game. In fact it didn't obey the time control at all! It was a Capablanca random Chess game with a...

Re: Fairy-Stockfish 10.3 released

Of course it can, because the list of supported variants of course got longer. That is why I asked you to try the non-large-board version of 10.3, because that one roughly has the same number of supported variants as the large-board version of 10.2. I just wanted to make sure that the bug definitel...

Re: Fairy-Stockfish 10.3 released

It seems that WinBoard crashes, which almost by definition is a WinBoard bug. String handling in WinBoard unfortunately is not very robust; it mostly doesn't test for buffer overrun, and just relies on all text buffers being large enough. (Currently set to 512 bytes through the macro MSG_SIZ.) Perh...

Re: (Some Winboard HELP?? HGM!!)

The output looks perfectly fine, so apparently Fairy-Stockfish is working well with the adapter. Please make sure that the command you are using in Winboard calls the adapter in the same way as you do it via the command line, because my only explanation is that this is not the case, otherwise WinBo...
