More Fun in Big Pots

[The Dude]

Bellagio 30-60. UTG is a TAG who almost gets poker. I'll ask you about the rest later.

Preflop:
UTG raises. 4 coldcallers to The Dude in the CO who calls w/ 5[img]/images/graemlins/spade.gif[/img] 4[img]/images/graemlins/spade.gif[/img]. Button 3-bets, BB calls, UTG 4-bets, everyone calls to Button who caps it. Again everyone calls.

Flop: (40.33 SBs) J[img]/images/graemlins/diamond.gif[/img] 5[img]/images/graemlins/heart.gif[/img] 3[img]/images/graemlins/heart.gif[/img] <font color="blue">(8 Players)</font>
Checked to The Dude...

Against what types of players on the button should we be donking this flop?
