Hi Anthony

I haven't found anyone who habitually writes chess in assembly language. I do
but then I'm an eccentric old amateur. Some of the programmers would be quite
capable but wouldnt see any point, some think in terms like "assembly tricks"
and have only a sketchy concept of assembly - like my concept of "C".

There are MASM, NASM and TASM available among other assemblers. People recommend
Nasm and Tasm to me but I (awkwardly) just use my debuggers - mainly GRDB.

I program for fun and chess is fun to program.

Regards

John
