$2/4, 11pm.

V1: Reg LAG pro. Sometimes gets out of line but has been playing fairly snug this evening so far ($650).
V2: Competent player ($250).
V3: Drunk rich fish. continually bluffing when it makes no sense (and showing), triple barrelling with air, calling down with A high etc ($450 - second re-buy).
H: white, mid 20's, competent tag, tight table image ($550).

Action:
V2 limps, V3 in CO limps, H on BTN with KJ raises to $25. i'm pretty much making this play to iso V3. V1 flats from BB (Wasn't expecting this as I know his game somewhat and he hates playing OOP, so I am putting him on a tighter range than usual), and V2 calls. Pot: $102.

Flop:
KJ10
V1 and V2 both check, V3 donks for $35..
H? I'm thinking here a raise is probably optimal but my question relates really to the sizing, w/ respect to V1 and V2 as well.

Definitely raising here. This is a connected board, multiway. I like raising to $135, which sets us up to effectively shove on turn.

Raise, although I'd go more than the $135 suggested. Probably like 150 - 160 leaves you slightly less than a PSB on turn.

The raise tests and squeezes V1 and V2.

If either of them call or raise we are probably beat.

With the stack sizes I wouldn't mind if they told us where we are at…

… so we can fold to further action unless another the turn brings another K.

I wouldn't be so quick to raise and take away initiative from a player who bluffs too much. What I would do in this spot probably depends on how big of a turn bet I expect if I just call and no one check-raises.
