NL100 Overpair vs. TAG on ugly board

[bigoliver]

I reevaluated the turn and didn't want to play allin on the river here. What would you have done in that spot? MP3 calls 2 times and I guess with his stats he does that with a medium pocketpair and could easily hit his set here. I noticed that i am to scared sometimes but i think here fold was correct.
He leads immediatelly even though he is not the proflop aggressor....
