SIMPLE 100/200 HAND. RIVER DECISION.

[flawless_victory]

party 1/2.
i raise JdJs cold stone UTG. villain coldcalls EMP, everyone else folds.
villain is a regular in the game... he plays a little too loose, but hes ok after the flop... really typical 1/2 internet player, i think.

flop comes down A [img]/images/graemlins/diamond.gif[/img]6 [img]/images/graemlins/diamond.gif[/img]3 [img]/images/graemlins/club.gif[/img]
i bet, he calls. hmmmm.
turn 2 [img]/images/graemlins/diamond.gif[/img]
i check, he bets (of course), i call.
river Q [img]/images/graemlins/spade.gif[/img]
i check, he bets....
okok. call or fold? what can i put him on here?
i cant put him on 66 bc i assume hed raise the flop hoping to get action from me if i had an A... most of the hand he might play preflop that make a flush arent possible bc i can see the Jd (and the A)...
is he really gonna coldcall EMP with A high? i fell like ppl are going to call an A63 flop with no hand just hoping i will check/fold a PP on the turn, so i feel like my hand is often still good on fourth, but then he bets the riv.
do ppl bluff here in internet games? in live games ppl bluff here all the time, but live players muck JJ w/ the diamond on the end... internet players, not so much.

so... should i be looking him up on the end?
