Thanks for the new version. For what it's worth, 1.4 solved the Mate in 22 problem here on the forum significantly faster than the 1.2b version I was using before.

Never use the RoundRobin-mode of the LittleBlitzerGUI for your testwork. In the RoundRobin-mode the LBG chooses the opening positions per random out of the opening-positions-file and will not replay the position with reversed colors. Only in the Gauntlet-mode the opening positions are played sequentially from position 1 and replayed with reversed colors.

P.S: Testrun of Black Mamba 1.4 for the LS-ratinglist is running. Result in 5-6 days...

Mateo, It seems that the users have problems with the 32 bit.
Maybe let code larges pages ...

[Mdannib]

Thank you, Jose.
The problem is the code used for the large pages; i will prepare a new compile for oldest pc (only for 32bit) asap but without any test (al my pc support the large pages).
There are some problems even with the Mac version running on Osx 10.5 and 10.6 but i've already got the fix

You must completely disable large pages to 32 bits,

To my knowledge no 32-bit system supports them.

By the way, I probe BlackMamba with the Blockade pawn activated and had no breakage.

[Mdannib]

Some news.....
* Added the file BlackMamba_1.4_Win32_NLP for the systems that doesn't support the large pages and got the error related to KERNEL32.dll
* Recompiled the mac version that now runs on OSX 10.5 or above.

The NLP version is not tested
