Reverse floating means you float your opponent out of position with plans of bluffing them later.
Reverse floating usually occurs when playing hands from the blinds.
This is referred to as a ‘reverse float’ because you are floating your opponent out of position.
EXAMPLE OF A REVERSE FLOAT
You call pre-flop with KQ, and the flop comes 753.
You check and your opponent bets.
You choose to float him with your KQ, as it might be the best hand and you have outs.
The turn goes check/check to the river.
On the river you bluff-bet into him.
This is a successful reverse float. You float him on the flop, and when he shows weakness or shuts down on the turn, you bluff the river.
Though the reverse float can be effective, it is a better play overall to execute when in position.
