$5/$10 6 max. Its my very 1st hand at the table and I have $200 in the BB.

3 limpers. I check my [6c].

Pot $40. Flop [7s][4d]. SB checks, I check, UTG ($450) appears to be a total donk from the one hand I just watched him double up with. MP ($500) raises to $160. SB ($1800) cold calls.

I have nothing invested but I can get all in and possibly triple or quadruple up if I hit my straight. Of course I may only have 6 outs and not 8.

What do you do?

I folded but did it without thinking. I think vs UTG who I just saw make a boneheaded play and the other short stack who I assume by default is a moron, I thinks its a push.

I messed up the stacks a bit. It went like this

UTG ($750) limps
Button ($465) limps
SB (big stack) completes
I check my 65 in the BB

So the flop was [7s][4d].

UTG bets $40. Button raises to $160. SB calls, I fold and UTG calls.

Pot $520. Turn . They check to the button who shoves in for $295. SB reraises all in and UTG calls off his last $585.

UTG has [8s]
Button has [2s]
SB has [7d]
