GES_136 available

[David Weller]

Tweaks to King safety and especially extensions

Null move condition added: beta > -MATE+300 [ie., must NOT be getting mated]

Also, do not do MATE_THREAT_EXT if already getting mated
same with 1 reply to check

ADDED 'capture into ending' extension where, if 0 < material <= minor for both sides, extend 2 ply - seems to help

fixed some errors with my [poor] 'CANWIN' code

Still does not recognize opposite color bishops, which has cost it a couple of draws I think

My last 'Titan' match GES won 13.5 points!

Hi,

Does it compile under Linux? (tried compiling Ges 1.34 - did not work).

Hi Pallav,

Someone once did a simple mod, to compile under linux, which was suprisingly easy [he had to do a little edit of 1 or 2 files]

mostly in utility.cpp

I know that in order for gcc to work, there are some unsigned longs which will need the UL appended to them in book.cpp

Maybe some day, I'll take the time and make it right. But I am an inexperienced programmer, at most, so its not easy
