2-40 spread hold'em hand

[brick]

not sure where to post this....

1-1-2 blinds, 2-40 spread game in Seattle because the law caps bets at $40. This game is playing huge compared to the blinds. Most pots are raised to 10+ PF, one or two $40 bets usually go in. Stacks are mostly deep.
Players are not very good in general, although they have all played limit hold'em for years. (myself included)

UTG limps, LP Limps, I raise to $8 with Jc9c because I like the pots to be bigger when I have position.

SB calls, BB folds, others call. 4 to the flop for $8 = $24

Flop Qc, 7c, 2c

BB checks (short stack, unpredictable dealer), UTG bets 20 (likes to gamble), LP calls (middle age entrepreneur, knows poker, but might like to gamble).
I raise to 60, BB calls, UTG 3-bets to 100, LP calls, I cap 140. All call.

Turn: 6h
Checked to me, I bet 40, SB raises all in for 80, UTG calls, LP hesitates and calls, ….. my action?
