Ducks are good? Good aggro betting or pissing $$s away?

[jayrutz2]

Party 2/4 - Table is aggro pre-flop, tight weak post
Hero is button with pocket 2s

4 calls to hero who limps. SB raises, BB reraises, ALL call to hero, hero calls (and readies to match cap, holding his stomach in disgust and thinking what the f am I doing) SB caps, all call. Seven players, 28 SB.

Flop 3,4,6 rainbow. ALL check to Hero

Hero...bets. 4 callers, no check raise. 15.5 BBs, 5 to turn

Turn 7 (put flush draw out, but not mine)

All check to Hero again! Hero, seeing his weak gut strght draw gone, thinks who the f#$K is trapping me...swallows and bets, ready to fold to a check raise.

SB calls, all others fold! 17.5BB to river, 2 players.

River : 4 (not 3 flush)

BB checks, Hero says, well, try to win it and bets, thinking he might fold and overpair to the dueces...

So, are the ducks good? Does SB fold? Was Hero playing good aggro poker or pissing away money? Results not-withstanding, comments on all streets welcome and appreciated!
