...pretty much handing over 4.5 Big Bets to the guy to my right.

CardSharpCook referred to my J9o made str8 fold to a raise on the Turn as "Donktastic," (lol) so
I feel obligated
to share some more donkness with you all to help you not make the same idiot moves as me.

How bad was this:
$5/10 Limit,
folded to me in SB with 33. I raise, BB calls.

Flop comes a 7 A 2 rainbow. I bet, BB calls.

Turn: 9. I bet, BB raises, I call down. He flips over AQo for a pair of As.

How bad does this suck? What's the correct way to play a hand like this
(w/ "showdown value" like an A or any ppk. pair?).
Since I suck so bad, should I
consider just folding these hands in the future? (if I'm going to just be throwing Big Bets around like that?) Thx.,
