6/12 Laydown - Is this what Ed Miller means by pot's too big?

[iversonian]

Limped on button with Ad3d. 6 to an 9-5-3 flop with 2 hearts. Bet from EP and 5 of us see the turn for one bet. Turn is Ac, putting a 2-flush of clubs on board. Bet by player to my right, I raise, two players cold call, bettor 3-bets, everyone calls. River is 8h, check-check-bet by the turn bettor, I fold. Results to follow.
