Implied Odds 2 to the flop

[2Tone]

I’m still working on better understanding implied pot odds, but I’d say they don’t apply here. The scenario you present is heads up, so unless we are talking about a tourney situation where he’s a short stack and would already be committed, there’s only so much money you’ll be able to get out of him if that flush hits. As you say, it’s not like he’s not going to see that it is out there.

Implied odds come into play more often in multiway pots, or in situations where you have the possibility of hitting a full house to beat a flush.
