[Ed S.]

Seat 1: s1n7ense ($7.75 in chips)
Seat 2: HERO - 99 ($26.25 in chips)
Seat 3: chippman ($20.15 in chips)
Seat 4: lcangel ($8.15 in chips) Seat 5: TinkerBell17 ($31.60 in chips)

Seat 8: 7days jdubs ($20.95 in chips)
Seat 9: AAvKK ($20.70 in chips)
Seat 10: Lepedidus ($14.75 in chips)
ANTES/BLINDS
Sayry28 posts blind ($0.15), ginner x posts blind ($0.25).

PRE-FLOP
7days jdubs calls $0.25, AAvKK bets $0.80, Lepedidus folds, s1n7ense folds, HERO - 99 calls $0.80, chippman folds, lcangel folds, TinkerBell17 folds, Sayry28 folds, ginner x calls $0.55, 7days jdubs calls $0.55.

FLOP [board cards QC,QD,4D ]
ginner x checks, 7days jdubs checks, AAvKK bets $2, HERO???

Hero has pocekt 9s here.

Should I have called the flop and raise the turn on any non scary card? Or should I have just mucked it on the flop. What about re-raising preflop? Comments, suggestions, ideas?
