At the risk of being accused of stagnating modern-compiles and general computer progress etc ....
The 64-bit Mc-Brain 4.0 "generic" compile from Monge doesn't work here. As soon as I click on the generic 64-bit, I get an error message: xxx--engine has stopped working. Same for Stanback's and all of IP's SF-McBrain-4.0sm-Final & SF-Mc-Brain-4.0-Final compiles - all his 32-bits inclusive. I'm not exactly sure if his 32-bits might be mistakenly mixed.
My OS system: Windows 7 64-bit. Intel Q6700 Quad. HP Pavilion Elite. Yep, some of "us" still exists with this outdated processors
Sorry for any inconveniences. Thanks in advance for any accommodation relative to compatible compiles.

The 32-bit version is tested on a dinosaur, AMD Turion 64 X2 Mobile, running Windows XP 32-bit, and works well.

Re: SF-McBrain 4.0 Release
BTW Vincent L. You wrote in fishcooking, that SF can't solve this position. Are You sure? 19.12. version solves in 1-2 minutes.

Obviously SF solves 1.Nab3+ only with tablebases! Also Houdini and Komodo solves it after 1-2 minutes.

I tried just now with my slow 32-bit machine.
Plays correctly Nab3+ then Nb5 with a +10.00 in just 2 seconds
Cleared hash on each run. Gets it correctly 8 times out of 8 in
less than 2 seconds.
SF dev ver. 17122610
MultiPV==2
Hash 256MB
Windows OS
TB/Syzygy: Off
Cores: 2 @ 2 GHz
Maybe the MultiPV is a kind of cheating, but it gets 1.Nab3+ in less than 2 seconds.
Would also try with McBrain ver 4.0, later
Edit: oops forgot the "Thank you" line.
Thanks for this version 4.0 Mike!

Re: SF-McBrain 4.0 Release
Why would Sf need tablebases for this? Stockfish with Enhanced Verification Search added to codebase 2017-12-17 does not seem to solve it on one thread, 512 Mb hashtables. No Syzygy. The same version without Enhanced Verification Search also did not solve it but I only tried it for three minutes. Are you guys sure this a Null move problem.Jouni wrote:Obviously SF solves 1.Nab3+ only with tablebases! Also Houdini and Komodo solves it after 1-2 minutes.

Debugging is twice as hard as writing the code in the first
place. Therefore, if you write the code as cleverly as possible, you
are, by definition, not smart enough to debug it.
