100NL: I Hate Middlestackers

[Kos13]

I just sat down a few hands ago. SB is ~35/1. MP1 and BTN are both bad sLAG's who respect my 3bets, and since BTN was the only one of the three with a full stack, this seemed like a really easy spot to squeeze.

UB NLHE - $0.50/$1 Blinds - 10 Players

SB: $47.75
Hero (BB): $100.00
UTG: $48.50
UTG+1: $99.05
UTG+2: $100.00
MP1: $41.25
MP2: $99.00
MP3: $82.50
CO: $128.90
BTN: $110.30

Preflop: Hero is dealt Q[img]/images/graemlins/heart.gif[/img] A[img]/images/graemlins/club.gif[/img] (10 Players)
3 folds, <font color="red">MP1 raises to $3.50</font>, 3 folds, BTN calls $3.50, SB calls $3.00, <font color="red">Hero raises to $18.00</font>, 2 folds, SB calls $14.50

Does anyone not make this move PF? Why not?

Flop: ($43) 8[img]/images/graemlins/spade.gif[/img] T[img]/images/graemlins/spade.gif[/img] 7[img]/images/graemlins/club.gif[/img] (2 Players)
SB checks, HERO (Villain has $29.75 left)

What the hell? Do I take the free card? Is he ever folding if I shove? This is obviously not the dream flop...am I just [censored] no matter what I do?
