Stuck in airport, found a 5dollar box of chips, bought said chips, had tournament.

10players all started out at 100chips, down to three

Blinds of 10-20

SB: 500
BB: 50
Me/button: 450

Preflop;
Raise to 80
SB calls
BB calls (all in)

Flop
SB Checks
Me: Bet 100 (Trying to show weakness? Bad call?)
SB Calls:

Turn
SB: Checks
Me: ???

Is the flop poor? Should I be shoving the flop?
Do I lead the turn? Do I fold preflop?

On the turn,

1/ No worse hand calls
2/ No better hand folds

Pretty easy check behind then. Probably fold to a river bet unless you really think he's trying to bluff you off for the sidepot.

Thats really not the slop you wanna try and show weakness on.

I woulda thrown out around 150

easy check behind on turn
