Free card play - Do we use it enough? Dicussion.

[K-mac]

Correct me if i am wrong, but raising with a flush draw against 5 opponents isnt raising for a free card. Arent we raising for value there because we expect to make our flush 35% of the time agains 5 other players (givign us a HUGE equity edge)?
Also the assumption is by raising the passive players will check to us and we are saving a small bet or so to see our hand all the way through. Again this is assuming the players are very predictable.
