Too fancy or just right?
 

Button is solid, probably 2p2. 27/22/2.4 over 408 hands. Havent seen him get out of line, and I have seen him make some nice plays like calling down with ace high against a LAG, isolating a LAG, laying down to turn raises from solid predictable players, etc. He probably has a good line on my play also which is a good mix of straightforward and semibluff, etc. I expect his button raise to be loose, but not garbage. He uses his position well to stay in control of a hand.

Hero has KQo in the BB
Folded to button, who raises.
Hero calls

Flop KQ7 rainbow. Hero checks, villain bets, hero raises, villain calls.

Turn comes 3h, putting a two flush on the board. Hero checks, villain bets, hero raises, villain calls.

River is 2h, filling the flush. Hero bets, villain calls.
