Hero is on CO with 4sTsJcQh 950 Eff.
Straddle is a LAG-Fish, who is stuck.

All fold to hero who pots to 20, BTN, sb, and bb folds. Straddle 3-bets to 67.5, hero calls.

Flop: Js9s4c (140) Straddle c-bets 60, hero raises to 200.

Alright my open is a bit questionabel, BTN was very tight so I expect him to fold about 90%, sb is tight-passive.
BB and Straddle are value. In general we expect to play IP vs 1-2 whales when we raise. This has to be more
profitabel then folding I would guess. Feel free to disagree and why :)?

On the flop I assume his holding is Random hands like jxxx/9xxx + gutters and QQ+. I would not expect him to have FD often here since that is a hand I would assume a stuck villian to bet more with. What is a good way to get maximum amount
into the middle against that range? If not why would a call be better?
