PL100 - Middle set on scary flop

[mason55]

I'm in BB with T[img]/images/graemlins/spade.gif[/img] T[img]/images/graemlins/diamond.gif[/img] 8[img]/images/graemlins/heart.gif[/img] A[img]/images/graemlins/spade.gif[/img] with a $100 stack. Still learning how to deal with these situations. Standard? Be more aggressive? Different bet size on river?

UTG calls, UTG+1 calls, MP1 folds, MP2 calls, MP3 calls, CO folds, Button calls, SB folds, I check.

Flop is T[img]/images/graemlins/club.gif[/img] J[img]/images/graemlins/club.gif[/img] 8[img]/images/graemlins/diamond.gif[/img]

Checked around to MP3 who bets pot ($6.20). I call UTG calls.

Turn is K[img]/images/graemlins/club.gif[/img]

I check, UTG checks, MP3 checks.

River is 8[img]/images/graemlins/spade.gif[/img]

I pot for $23.85

Thanks a bunch
