the worst best fold I have ever made...

[stealyourface]

Sorry I don't have the hand history but here goes...

No reads on villians as I sat down recently.

Party NL50

Hero - 45
SB - 50
EP - has us both covered

EP makes it 3 preflop, and I call with 8-10 of clubs in MP. SB smooth calls and its 3 to the flop.

flop: 10-10-3 r

SB bets out 6. PFR smooth calls. I smooth call (thoughts?).

turn 9 completing rainbow.

SB bets out 20. PFR pushes putting us both all-in. I think and I think and I reluctantly muck.

I was pretty confident I had the PFR beat but the SB threw me off. Is this too weak/tight? does anyone else fold here?
