Most flops are.....

Okay, thanks, now I get it. Wish I could get this down once and for all.
How does this affect preflop play? If you have suited hole cards then your chances of flopping a flush draw are about 25%. Does that make it worthwhile calling a preflop bet up to 4 x BB?

Read post 31 by pdk1010 in this thread. It shows the probabilities of the different kinds of boards you can flop with a suited hand (flopped flush, flopped draw, 1 of your suit, none of your suit).

Even if you flop a draw, you're still only 35% or so to make it by the river.

Ultimately, the decision to call a 4xBB bet with a suited hand hoping for a flush is very situational and relies on implied odds. What are the stack sizes? How many people are already in the pot? Will someone behind try to squeeze you out? Will your opponent pay you off if you hit? Will he play too aggressively to be able to get to the river on just a draw? Do you have any steal equity postflop to make it profitable even if you miss hitting a flush draw? etc.
