Ok, I'm trying to understand pot odds and won't swear I've got it.

So this was during the FTR500 last night and someone pointed out that I should have called this hand due to pot odds...

Wait... converted the wrong hand... just a sec... ok this is the right hand...

So I am near the end of the FTR500 and don't want to be overly risky, but this hand came up and I looked at my cards, the player to my right goes all in, then I fold. People questioned my fold, but here was my logic:

Ah hell the trimmer screwed it up, here it is raw:

Full Tilt Poker Game #6304724878: The FTR500 (46876860), Table 2 - 150/300 Ante 25 - No Limit Hold'em - 23:53:17 ET - 2008/05/05
Seat 2: jolub (808)
Seat 3: Monty3038 (4,233)
Seat 7: dwarfman1990 (13,381)
Seat 8: renegades8 (4,706)
Seat 9: SuitsUs (18,372)
jolub antes 25
Monty3038 antes 25
dwarfman1990 antes 25
renegades8 antes 25
SuitsUs antes 25
jolub posts the small blind of 150
Monty3038 posts the big blind of 300
The button is in seat #9
*** HOLE CARDS ***
Dealt to Monty3038 [Jh 6c]

So I've got nothing, just a Jack High, which is crap.

dwarfman1990 folds
renegades8 folds
SuitsUs folds

jolub raises to 783, and is all in
Monty3038 has 15 seconds left to act
Monty3038 folds
Uncalled bet of 483 returned to jolub
jolub mucks
jolub wins the pot (725)
*** SUMMARY ***
Total pot 725 | Rake 0
Seat 2: jolub (small blind) collected (725), mucked
Seat 3: Monty3038 (big blind) folded before the Flop
Seat 7: dwarfman1990 folded before the Flop
Seat 8: renegades8 folded before the Flop
Seat 9: SuitsUs (button) folded before the Flop[/b]

So I was 300 into a pot of lets say 1500 already, with needing 483 to call, which means the pot gave me roughly 3 to 1 odds, or spending 500 to win 1500. All I needed was a 33% chance to win to make it a good call, correct?

I don't think that J-6 off gives me those odds, so I folded... am I wrong here?
