Tricky play describes the integration of certain moves into your game in order to extract more value from your hand.

When you play tricky, you will often deviate from your standard game with simple value bets and try to mislead your opponent a bit.

You could do this for example by skipping your continuation bets against certain opponents who like to donk bet the flop, if you think you can extract more value that way. Other important keywords here would be check/raises, inducing bluffs, floats or bluffs in general.
