Set on the Flop

Sets on the flop are tricky to play. The correct amount of aggression
is board dependent.
On dry boards the set is very strong. A set against top pair is over
98% favorite. It's safe to bet small and attempt to string opp along.
You: 6s6h
Flop: 9s6c4d
Opp with As9h is way, way behind. Needs runner/runner to beat you.
As boards become more coordinated they become more dangerous.
Sets should fear flush and straight draws. Plan a betting
scheme which denies opp both pot odds and implied odds. On
these types of board sets want to be all in by the turn.
The river betting favors the chaser.
