Sweet hand! I'm down $200 and $400 for my last two sessions AND I don't use any kind of math when I play so I probably should be the last person offering any kind of feedback BUT, For My Group, I'd probably make them pay more for their draws on every street, including a little more pre-flop. 2 main reasons, if someone else also has AK, I'm free-rolling them with the diamonds and, in our games, I don't know how many times a hand and board like that has lost on the river - somebody who was hanging around hanging around (haha) got there and what looked like a nut flush on the river lost to a straight flush and/or nut straight/nut flush on the flop/turn ended up losing to full houses when boards paired up on the river... It's so sick in our games (even when only playing 3 way!) that I should probably come up with a new custom set of chips with "Cooler City" somewhere on them!
