Okay, it's clear that I don't know how to play this sort of hand. I have no real plan here I was playing it by ear.

Hope the format is readable, doesn't seem to be any Everest convertors out there (wonder why.. ).

Deal Pocket Cards:
Hero: 5c 6c

Don't normally play these, certainly not so early, but am on the button so I thought I'd give it a go.

Pre-flop:
UTG calls, 1 fold, UTG+2 calls, MP1 calls,
1 folds, MP3 calls, CO calls, Hero calls. BB Checks.

Flop (Qc 9c 2c):

Okay, I've made my flush but it's a low one. The only possible flush hand that could lose to me is 43s.. what're the odds of someone else hitting their flush on the flop?

BB checks, UTG checks, UTG+1 raises 7.00,
1 fold, MP3 calls, 1 fold, Hero raises 14.00
2 fold, UTG+1 raises 14.00, MP3 calls, hero folds.

I took the line that if he called me I'd go after him but a confident re-re-raise was strong enough to make me suspect a strong flush. So I folded to the re-re-raise.

Turn (Qc 9c 2c Qd):
UTG+1 checks.
MP3 raises 35.50 (All-in).
UTG+1 calls 35.50.

River (Qc 9c 2c Qd Jh):
Showdown:
MP3 shows 10c 6h.
MP3 has 9c 10c Jh Qc Qd: Pair
UTG+1 shows Qs 5s.
UTG+1 has 9c Jh Qs Qc Qd: Three of a Kind

So, layed down the winning hand. What can I learn from this (other than don't play suited connectors until you know what you're doing...)? Commit to a do-or-die in this situation? Continue to give in to strong resistance?
