another EP problem

[jaydoggie]

11$ 1 table SNG on 'stars. Blinds 10/20
in the BB with A[img]/images/graemlins/diamond.gif[/img]9[img]/images/graemlins/diamond.gif[/img]

4 see flop pot (90)
9[img]/images/graemlins/heart.gif[/img] 6[img]/images/graemlins/heart.gif[/img] 4[img]/images/graemlins/club.gif[/img]

i fire out 60. chip leader (2900) calls. other 2 fold.
immediate thoughts, flush draw/straight draw. no raise preflop eliminates big ace from my mind. at this point im not even thinking AA/KK trying to trap. ordinarily if someone limps with these hands trying to raise, and it backfires, they get ultra paranoid and try to push for the pot right then.

turn J[img]/images/graemlins/club.gif[/img]
i fire 100. he calls.

river Q[img]/images/graemlins/club.gif[/img]
i fire 100 again. he folds.

problem: assume he WAS chasing hearts. im unsure since he didnt show. as the lead bettor its impossible to know if he's holding Qx/Jx/Kx so how does anyone else deal with seeing running over cards fall, vs a very vulnerable TPTK.

i assume if i give up on the pot and check to him, its me screaming, please take this pot from me. same with a weak bet. one the other hand if he did end up catching his pair, or even two pair i dont want to be donating my T$.

did i play it standard enough, or is there a rule of thumb anyone uses in situations like this?
