10/20 loose table with many players like to limp pre-flop

5 limpers and i am bb ($3300) with Qs9c, i check, pot is $120

flop Qd9h2h

sb check, i bet 140 (i want 1 caller and push them on turn card if no flush or open end-straight draw hit on turn), i dun mind to just take down the pot now as my position not good.

mp (always limp preflop but tight after flop, $4600) raise to 450, dealer (a new-joined foreigner) all-in with his 1500.

what will u do?

toronto & pb, same thought as yours after 10s thinking, i fold!

i tell many lisboa players and they 5 tell me shove, 1 tell me call, 1 tell me fold.

what i put them:
1. mp: either 2 pair or hit a set.
2. i dun put he get a set as he dun raise pre-flop (except he get 22), i put him get a flush draw.

as i am not pot-committed, i fold.
mp instantly called.

2 trash cards for turn & river.
show down:
mp: Q9 (same hand as me)
foreigner: 92

if i call/shove, i can split that 1500 of foreigner, but i like my FOLD (dun want gambling for my whole stack!)!
