I reduced my range on the flop not by which section my hand fell in, but by what hands could possibly have made it to the flop the way they did. Notice AA is not in there because it would almost always 3bet but A6s, 33, and T9s are possibilities because I would sometimes call with those hands.

It would surely simplify things if I only used my B) preflop range for the rest of the hand, though =p

Also on turn I wrote b/c rather than b/3b because I figure if he raises the turn it'll be a shove. What I meant was, "lead out and get all the money in if he raises."

Thanks for the feedback. It's interesting that, although my version of the analysis is more thorough and misses less options, yours is both more elegant and leads to the 100% correct hand read while mine leads to a bit a of a jumble! There's a good lesson in there, no doubt.
