gambling back-to-back with JTs against same foe

[brick]

20/40 diamond lils
I've have a tight image, and I'm down little due to not seeing many showdowns. Most players are average, not way loose but not tight by any strech.

Hand 1:
Game is short 6 handed with three walkers. Foe limps (seems like a decent early 40's asian player), LP raises, SB calls. I call in the BB with JcTc.

4 way to Flop: Qs 9s 4d
sb checks, I check, EP bets, LP calls, sb folds, I call.

Turn: 9c
I check, EP bets, LP calls, I call.

River: 5s
I check, EP bets, LP folds, I raise.


Hand 2:
Two of the walkers decide to post just behind our foe.
Foe raises UTG, two posters call, LP calls, button calls. I 3-bet from the SB with JsTs. BB folds. Foe caps.

One poster folds, Others calls.

5 ways for 11BBs. I check dark. (Rain Khan type mistake?)
Flop As Kd 5h

Foe bets, poster folds, LP calls, Btn folds, I check-raise, (for the oop free card, seriously), both call.

Turn: 7c
I stare for a second and check, check, check.

River: Tc.
I check, foe bets, LP folds, I call.
