Turns out I needed poly(e') + (X + 1) * (sup + max).
Went and played Go at the 61c with Charlie Smart.
and Grant Reaber. Charlie beat me once, and a
guy there named George beat me twice on a 13x13 board,
once with 3 handicap stones, and once (even worse!) with 4.
It's really fun to play such a decidedly decent opponent.
Charlie says Fred (another Pgh Go club regular apparently)
only loses to George when the latter has like 7 handicap stones.
