I was just talking from a maths point of view, that sort of situation depends on all sorts (reads / texture / etc). However, surely if we believe our flush will be good at showdown then its a call?

Hmmmmmm sorry I'm just tryin to work this out in my head - kinda thinking out loud here. Obv our flush isn't going to bethe best hand at showdown all the time, so we need better than the 1.85-1 odds to call, so the situation you outlined is probably a fold, other situaltions its a call (such as AQs with TP or something...)
