Think along with me on this Party Super Tuesday bubble hand

[allenciox]

There are 160 players remaining, 120 get paid. Blinds are 300/600, villian is in CO+1 with 6300TC, I am in SB with 9200TC (slightly above average stack) and get dealt Jc9c. Villian frequently limps preflop. All fold to villian, who limps in. I complete the SB (anybody who would fold here need not read further), BB checks.

Flop (Pot:1800): Qc Jh 8s

Do you 1) check-fold, 2) check-call, 3) bet out, 4) check-raise all-in? I chose to bet out 1200 with second pair, a gutshot straight and a backdoor flush draw. BB folds, villian calls.

Turn (Pot=4200) : 3d

Do you 1) bet (how much?) 2) check-fold, 3) check-call?
