Here is another one from my collection that is bothering me:

PokerStars Game #15729857180:
Hold'em No Limit ($0.01/$0.02) - 2008/03/04 - 05:37:25 (ET)
Table 'Adalberta' 9-max

Seat 2: BB ($3.47 in chips)
Seat 3: UTG ($1.79 in chips)

Seat 6: MP ($3.30 in chips)
Seat 7: CO ($2.90 in chips)
Seat 9: Button ($2.28 in chips)

*** HOLE CARDS *** Dealt to Hero [Ad Qd]
UTG: folds
UTG+1: folds

Hero collected $0.34 from pot

Obviously I flopped a monster here, so I was looking to get the pot as big as I could, but my 2/3 pot size bet was too much for the villain. Assuming a standard micro stakes NL table, do you think this was just a matter of bad luck - MP must've missed the flop altogether and I couldn't know that - or in heads up am I better to assume a hand like this will still be the best hand by the river and play it a bit slower to make sure I get some action?

Thanks!
