Please help me with this. (LONG)

[sng-sam]

This is not a SNG post but frankly I trust the advice in this forum above others. Not intended to be a bad beat story.

I am in need of some help. I play in a weekly live 1/2 NL game. Most players are fairly well off but they are terrible players. By way of example....

UTG raises $25 PF...MP2 calls.....Button reraises to $125...UTG calls.....MP2 calls....2 players are all in. Cards flip over....UTG has K[img]/images/graemlins/spade.gif[/img]K[img]/images/graemlins/diamond.gif[/img] .....MP2 has Q[img]/images/graemlins/heart.gif[/img]T[img]/images/graemlins/diamond.gif[/img] button has Q[img]/images/graemlins/diamond.gif[/img]T[img]/images/graemlins/heart.gif[/img] ...nuff said. Now on to MY problems.

$10 is the minimum raise in this game. Unconventional but the norm here.

Hand #1:
MP2 limps.....MP3 limps CO limps Hero (button) had A[img]/images/graemlins/diamond.gif[/img]A[img]/images/graemlins/club.gif[/img] Hero raises to $10 SB calls.....MP 3 calls.

Pot has ~$50...
Flop 4[img]/images/graemlins/spade.gif[/img]4[img]/images/graemlins/heart.gif[/img]8[img]/images/graemlins/spade.gif[/img]
SB checks MP3 Checks...Hero bets $50 SB reraises $80 Hero MP3 folds Hero calls (all in)

Showdown: SB shows Q[img]/images/graemlins/club.gif[/img]4[img]/images/graemlins/club.gif[/img]
Turn and River are no help

Do I not bet $50 on the flop here? I think I have to make a potsized bet here to protect against the flush? These are the typical ways that big hands get cracked in this game. Do I just accept this as the reality and realise that proper play will win more often than lose (ala Fundemental Theorem of Poker) or do I just stop playing in this game?
