Re: Mate in 19

Of course Peter, I wasn't absolutely sure that 19 was the quickest, but that was the best I could do. Where is the position from? It was discussed here before: http://talkchess.com/forum3/viewtopic.php?p=856600#p856600 But no hint to the origin there neither, even if I didn't read the whole thread....

Will there be an exe of this update? :?:

Only this makes sense.
Only source code is not usable for me and many others. :(


Somebody posted this earlier in this thread in which they said there was an executable (or compile) of Crystal there:

Re: Is 1. h3 Kf7 really better than 1. Be1 here?

It looks like you are correct, 1.h3 kf7 loses for white according to Stockfish, whereas it looks like 1.Be1 holds for white. The position After white moves 1.h3? 8/1p2b3/6k1/5p2/p2NbP1p/P1B1P1pP/1P6/6K1 b - - 0 1 FEN: 8/1p2b3/6k1/5p2/p2NbP1p/P1B1P1pP/1P6/6K1 b - - 0 1 Stockfish_20041621_x64_bmi2: 1/...

Re: Test position: Kasparov-Pribyl (1980) - very tough

It looks like the new RofChade 2.3 does a reasonable job on this one.

Re: Test Position a6!!

Crystal seems to be hit or miss for me. The only one that seems to get it quickly and every time is Sting (at least for me) Try Crystal in 2MV- mode, if you like too. Please forgive my ignorance Peter, but what exactly is 2MV- mode? is it PV=2? or is it something else entirely? Sorry, put the blame...
