Using a 0x88 board representation, it is possible to get under 150 bytes of Python at least. My starting point was an old article by Bruce Moreland.

I have no idea of what kind of approach the best solutions utilize, though.

0x88 representation is definitely the right way. By putting the dummy board on the left side instead of to the right, it's possible to get down to 105B of Python.
I guess you have to be Mark Byers to reach 100B...

i am a beginner, i should learn more about that.
