Stack sizes:
Hero: $48.75
UTG+1: $46.40
CO: $43.66
Button: $48.75
SB: $13.62
BB: $117.88

Pre-flop: (6 players) Hero is UTG with J:spade: J:diamond:
Hero raises to $2, 3 folds, SB calls, BB calls.

Flop: 5:diamond: 5:club: 6:club: ($6, 3 players)
SB is all-in $11.62, BB calls, Hero raises to $40.03, BB raises all-in $104.26, Hero calls all-in $6.72.
Uncalled bets: $69.13 returned to BB.

BB is 46/13. SB is a typical shortstack.

This seems like a spot where you're either way ahead or way behind. First I would take into account what type of hands my opponent has called raises with. I wouldnt think about the short stack because he could just have a 6 and make that move or nothing at all thinking he could pick up the pot right there.

Now, It's hard to image my opponent called an UTG raise with a 5 in his hand so I figure he has one of 4 hands...

Axs for the nut-flush draw
a mid pair.

Though I have encountered players cold calling with AA/KK and slowplaying me, in this case I would proably pay those hands off. It's just not that many hands I could see him having and other than the flush draw, thats not a scary board and I don't see quads pushing over the top on the flop.
