Reverse implied odds
A common example of reverse implied odds is a player drawing with a low flush draw.
Player A: 7h6h
Player B: AhTh
Player A bets $2, Player B raises to $6
In this situation, Player A has the decision to call, raise, or fold. Player A might be tempted to see another card to hit his low flush draw. However, the decision to draw may cost Player A a lot of money since higher flush draws such as the above are in Player B's range. If both players hit the flush, Player A will be forced to put his whole stack in the middle with absolutely no outs.
Therefore, players should realize the value of the draw and recognize that they could be drawing to the second best hand with much money on the line.
