I have $650 and V covers. Fish limps UTG+1, I open to $15 in MP2 with K♠ K♣ and V makes it $30 OTB, fish calls, I make it $120, V calls, fish folds.

Flop: T♣ 8♣ 6♠ Pot $277 I bet $140, V calls
Turn: 3♦ Pot $557 I shove $390

Although min-3-bet is often AA I've played with this particular player and I know that he can be much wider there. He's not bluffing with something like a suited connector, he has a value hand but he's much wider than AA.

What's your feedback on all streets? I'm most interested in preflop 4-bet sizing. I'd like to 4-bet a size that's actually balanced, meaning that I'm 4-bet bluffing the same size.
