Features:
uses Winboard protocol
runs on 1 CPU core
requires 64-bit Windows
requires "popcount" and "bitscanforward" instructions
main transposition table size if fixed at 128 Mb; total RAM use is 144 Mb
this version does not use endgame bit-bases or table-bases
no opening book

Estimated strength is around 2800 ELO (CCRL results not available yet, will add a link as they become available)

I can't get this engine to run on my i5.
I use Windows 7 Home Premium.

I get the following:


Anybody else have success with Fizbo?

Not working also in my I7 920 windows 7 64.

It seems to need a modern CPU to work. It works on my Intel Sandybridge laptop, but not on my AMD Phenom II X6.

Maybe it needs AVX support, first introduced by Intel with Sandbybridge, and first supported by AMD with Bulldozer.

"requires "popcount" and "bitscanforward" instructions" --- see Graham's original post.

Yes, and the machines above have that support.

You're right---must be something else.

Seriously, Windows must produce a crash log, or give some information about why/how the program fails, right? Maybe run it from a command line, under a debugger?

[Modern Times]

Well, it works on Intel Sandybridge, so presumably it must be something supported on those and later CPUs that isn't supported on earlier processors.

Awesome, another original engine. The more, the merrier. Diversity is good for chess programming in general. Shame about the choice of protocol, I'd have preferred it using UCI but, well, that is something for the developer to implement.
