Anything wrong here with small boat?

I'm not home now so I don't have exact stats, but MP3 is a PT moneybag icon and CO is a Tazmanian devil icon.

Is the push stupid/careless in that I'll probably only get called if I'm beat? A straight might stay in. It might look like I've missed my FD so A8 might call. Only 88, TT, 66 (and less likely 83, T3. Did I miss any?) beat me.

If I look at this from their point af view, I put you on a set at best post flop. you checked BB and then overbet pot post flop. I think the 3 pairing on the river scares me off any large bet.

I'm being results oriented here, but since I lost a big pot and pushed when I was behind I thought I needed to examine this hand more closely. I lost to MP3's 88 which I probably should have sniffed out. I actually got a little suspicious on the flop when the TAG MP3 player smooth called a bet and healthy raise before him, but I lost my objectivity when I rivered the boat. I still lose a big pot with this hand, but the thought of him holding 88 should have been a lot higher on my danger list.

Frickin' 2 pair has cost me big lately.

For me I have finally stated to recognize that if I play a hand like this, sooted gaps or connectors I will not accept any big bets if I hit TP, 2 pair or even trips. I'm looking to win a small pot. I need to remember what I limped for, if I'm looking to catch a a draw of some sorts, I am not gonna play this crap for TP. He seen the pair on board and he had top set. He new he had ya beat. You can also look at it as if you don't raise from the BB what is it you are trying to accomplish against 4 other players when limping, what do ya think they hold. Try to remember what you are trying to flop and anything else is muck.
