When the flop is 9 high, 63% of the time an overcard to the top pair on the flop will fall on the turn or river. I applied this concept in the folloiwng example:

$10 NL

Hand Actions
Stackin Chips dealer
glavon SB $ 0.05
Jawz AJd
kingtut24 Call $ 0.10
canuhandle Fold
Jawz Raise $ 0.40
Bigapp Call $ 0.40
Stackin Chips Call $ 0.40
glavon Fold
phatchillin Call $ 0.30
kingtut24 Call $ 0.30
pot = $2.05

FLOP: 4 9 3
phatchillin Bet $ 0.10
kingtut24 Fold $ 0.00
Jawz Raise $ 1.85
Bigapp Fold
Stackin Chips Fold
pot = $5.75

TURN: 6
phatchillin Check
Jawz Bet $ 1.50
phatchillin Call $ 1.50
pot = $8.75

RIVER: 10
phatchillin Check
Jawz All-in $ 5.05
phatchillin Fold
pot = $8.69

Jawz Mucks Cards
Jawz Wins $ 8.69

When my opponent called the flop on this flop I knew he had a pair of nines and punished him for betting such a weak hand on the flop. My point here is that on a nine high flop the aggressor will usually win unless their opponent makes 2 pair or better. If the turn and river card were both lower than ten I would have checked and gave up onthe hand, but this is rarely the case.
