Right Play, Wrong Result

I know most of you probably don't care about reading hand histories, but for those of you who do play, you'll see why I wanted to puke after I folded.

Sometimes doing the right thing can cost you. Like here, where I open a decent hand and make the "correct" play by folding when I get squeezed and the squeezer gets cold 4bet shoved upon. Except... I would've made a straight flush and stacked both of these guys.

Pre Flop: (1.40) Hero is MP with Q T
1 fold, Hero raises to 4, CO calls 4, BTN raises to 10, SB raises to 91 all in, 3 folds, BTN calls 81

Flop: (191) K K 9 (2 players - 1 is all in)

Turn: (191) J (2 players - 1 is all in)

River: (191) 2 (2 players - 1 is all in)

Final Pot: 191
SB shows A A (two pair, Aces and Kings)
BTN shows T T (two pair, Kings and Tens)
SB wins 181.60
(Rake: 9.40)

Still, I take some solace in making the right play, even if making the wrong move would've been profitable this one time. I had already decided to fold if anybody raised me pre, I was tempted when the first raiser only made it 2.5x my bet. But there was no way I was going to call a 4bet, let alone a shove with QTs. (The guy making the tiny squeeze and then stacking off with TT is burning money in this spot.)
