i'm a fish hand...2/5 NL at bellagio

[technologic]

forgot to post this hand...curious as to whether it's a good line

it's getting late at the bellagio, and i'm getting bored. me and my friend are about to head out, so i'm playing one last round...

2/5 NL bellagio, 9 handed no real reads on players involved

i get dealt 57o in the LP. UTG+1 limps, MP3 limps, i limp, CO limps,button raises to 25, UTG+1 calls, MP2 calls, so i call like the fish that i am, and CO folds.

flop is 554 with two diamonds. UTG+1 bets 25, MP2 calls, i make it 150 straight, button calls, UTG+1 folds, MP2 folds.

at this point i have him pegged on an overpair, but i'm not sure which...which comes to the worst turn card i can find.

a Kd. i have around 250 left, he has me covered. i move in.
