I've got an overpair - but with 55??

Hi,

So the following hand came up last night and I felt a little lost.. Pretty sure I made the right move (moves?) although I would welcome comments about the flop play - I think a fold may be in order since there's one player behind me but I'm not too sure.

Don't have the exact hand cos I'm at work but here goes:

9 handed NL $0.5/$1

Here is MP - dealt: [5, 5]

One limp, Hero limp, CO limps, SB raises to $5, one fold, Hero calls, CO calls.

Flop: 2 ,3, 3 (two clubs)

Pot ~ $19

SB bets $10, Hero calls, CO calls

Turn: 2 (still two clubs)

Pot ~ $49

SB bets $20, Hero folds, CO folds.


Thoughts?

SB has $100 ish, CO has $90 ish and I cover both.

Both SB and CO are fairly tight and seem to be competent players. SB doesn't seem too tricky (been playing 30 mins or so and I haven't seen any bluffs or moves shown down). CO is also quite tight but is a bit tricky and has re-raised light a few times (especially in position) but generally seems competent.

Once the second 2 hits I'm a little lost as I feel SB may well be betting an A here but with CO in the pot I think it's hard for me to call.

All feedback welcome!
