Re: Stockfish/McBrain 2.5 Release
Thanks for this release!
Looks like the 32-bit ones are working perfectly on my rusty machines. But both 32-bit labeled old and the generic 32 bit of this version seems to be working fine. Whats the difference between the two? Sorry if i missed some notes regarding the difference of these two Win32 compiles at your linked page.

Re: Stockfish/McBrain 2.5 Release
I don't have the bleeding edge Arena GUI, but on my old version Arena it is Ctrl + 1 {{or control + one }}. If you want the mouse clicking way just click Engine Menu, Engine1 McBrain > Configure. It is displayed at the left hand side of that window.duncan wrote:how does one access 'UCI-LimitStrength' in arena ?MikeB wrote:Details, Source and all flavors of Exe's are available here:

This engine looks impressive because the Null_Move option can be disabled/enabled without recompiling the engine. I have already tested some difficult positions which can be easily solved by McBrain 32bit version, haven't seen any 32-bit version doing this feat.

Re: Stockfish/McBrain 2.5 Release
hey michael, don't know if the 'readme' on the DL site is new or i just noticed it, but
at what level would tactical be set to to replicate the level of houdini 5 (or 3, since i think this is faster in some positions) tactical search? at what level do you think it goes beyond usefulness in the overwhelming majority of positions?
finally -- what settings would you recommend for, say 1hr analysis? 10min? (i assume default, maybe w/ some level of contempt) 30min? (i don't expect you to have any answer to these, & certainly not a definitive one, just asking out of curiosity)
is that for any (generally speaking) position, or extremely difficult positions with a solution?For overnight analysis, I suggest setting the matefinder option on , Tactical to 3 or 4, and respect to minus 15.
