Hero is winning V1 is a good thinking reg TAG .

V1 raises the co 800 eff hero calls on btn with khkd (he doesnt give much action vs regs and there are 3 fish behind.

Flop goes 4 (100) ways, flop is 479ccc. V1 bets 25 into 100 Hero calls others fold.

Turn 3d (150) Villian checks hero bets 85 V calls.

river 6h- V checks, Hero bets 185. Is this too thin? What hands can we get called by?

(He folded aa face up this is why im wondering if it is too thin.

Thanks
