Yes, my mistake, now corrected

Yes.  Now rewritten as you suggest.

I am interested to see that UCB does indeed have that effect.  We were 
discussing it this morning, and wondering if a pure UCB program would be 
happy about its opponent have a two-point group, expecting one of them 
to get filled in.

But I doubt this would be of general interest to programmers?

I've added all that now.  Thank you for explaining these differences, 
and for pointing out the other errors.
