Deepstacks $11 overbetting the nuts on the river.

[Cornell Fiji]

Not building the pot on the flop and turn is criminal.

Pot the flop.
Pot the turn.

He is never folding 79/J9/Tx/3x/hearts on the flop regarless of whether you bet 100 or 300 so build the damn pot!

When you flop a monster your goal should not be to get the most chips from a weak hand but rather it should be to stack a 2nd best hand.
