missing the flop in 3-bet pots

[chicheebee]

(this hand was played against a MSNL fish, so i thought it belonged here rather than HSNL)

so i followed a (38/22/2.8) fish up to $10-20 (which was higher than i'd ever played)


Texas Hold'em $10-$20 NL (real money)

Seat 1: Hero [ JC,AD ] ($1,048.00 in chips)
Seat 5: P5 ($3,022.00 in chips)
Seat 6: P6($170.00 in chips)
Seat 9: P9 ($3,347.00 in chips)
Seat 10: Villain ($1,043.90 in chips)

ANTES/BLINDS
hero posts blind ($10), P5 posts blind ($20).

PRE-FLOP

P6 folds, P9 folds, Villain bets $70, Hero bets $220, P5 folds,
Villain calls $160.

Real flop: FLOP [board cards 8H,JH,6H ]
Hero bets $400, Villain bets $813.90 and is all-in, Hero calls $413.90.

My question is: How should I play the hand if the flop comes down:
[board cards Qs 9h, 5C ]

(his att. to steal blinds % is 33)
