Quiz:
Preflop: 77+, AT+, A5s-A7s(ie some suited Ace stuff), KJs+, QcJc, 89s
Given the 3bet stat and VPIP/PFR, even v. an UTG raise, villain's 3betting more than just nut hands. With tecmo's stats (I don't see any 13/13 shaggy's talking about, I see 24/20), his UTG range has a fair amount of hands that will fold to a 3bet.
Flop: 77+, ATs, AJ+, A5s, A6s(ie some suited Ace stuff), KQ, QcJc, 89s
He cbets 90%. I tossed ATo, A7s, KJs and kept my SC representative. Very dry board so he probably figures to pick it up a lot vs. what looks like a mid pair or Ace-big. He could be discounting AQ from our range since one flopped. Based on his bet size, if he's not bluffing he's looking for value from a smaller pair than his own.
Turn: 77+, AQ, ~A5s, KQ, QcJc
He barrels any bluffs he wants to continue with, so he's got a value hand or gave up. He's got to partially at least discount the big Aces from tecmo's hands, but again, he barrels if he's trying to fold those out. So he has some value to showdown. A5s probably isn't in his range much, but it reps the Ace rag that caught a piece, so discounted but there. If he has a PP, he's showdown bound if he can help it, hoping it's bigger than tecmo's. Tecmo has shown an interest in the pot, so if villain's got a set of 9s, TP or JJ, TT, he's happy to induce a smaller PP or spazz from AK.
River: 77+, AQ, ~A5s, KQ, QcJc
Nothing happened on the turn, so same range. 7s and 8s are giving up probably even to a half pot bet. 9s full is obv. stacking off. AQ is calling almost always, and KQ calls a fair amount. QcJc calls some, let's say 50%. So we've got 3 combos of AQ, 3 for KQ, one half for QcJc, 3 combos of 99, one half for A5s, and 6 JJ and 6 TT. So 10 combos that will pay, say $36. Let's say half the JJ bluff catch, so another 3 combos for $36. That leaves half the JJ, TT, and half the 88 that will call, say $24 to bluff catch. Assuming all of the hands that call $35 would also call $24 (obv.), and 99 stacks no matter what, and AQ may spazz shove, and he might have exactly As5s that stacks, I say:
Bet $22-24
