3/6nl - what the hell does this flop bet mean?

[Stelvask]

3/6nl. just 3 of us playing at the table (just started a new FR table). We've only been playing for a few minutes. The SB has been most of the pots (though not the last two), and has been betting at most of them. He's shown the nuts once and a stone cold bluff once. He bet each hand roughly the same way (and no strange betting on either hand).

button folds and the SB raises to $24. I call out of the BB with [Qs].

$48 pot, HU. flop comes [2d][3h]. SB bets $138. I ???

i don't think you should fold. i'm just not sure if raising or calling is better.

I think hes got either nothing or something like K8. I flat call.

Wow I gotta start huge overbetting some flops with my big hands. Makes it very tough for KQ to get away here, doesn't it?

I have no clue what to do here. I probably call again but that feels like such a donkey way to play that I hate it.

I can't fold.

OK, this is what I do. I "think" and let that time clock run down a while, and then I call. If he's bluffing I want him to think I'm weak so he will bluff the rest on the river. The worst situation to be in here is one where he will only bet the river the times he's ahead.

Now I shove it in. Its really not the correct play but Im doing it anyway.

Thats exactly why I push the turn even though its not the most +EV play. I dont want to be put in that spot on the river when the board gets really ugly.
