Going all in on a flush draw.

[EsandWhizz]

A few months ago i read a post by Tien who said he was a winning 400nl player who was walking away from poker and wanted to give something back to 2+2 before quitting . The post was called 6max fundementals and the post massively improved my game at 50nl 6max to the extent that im in profit since reading the post. Anyway one point he made was to play flush draws hard and fast and be prepared to get all the money in the middle with the nut flush draw. Iv been following this advice and whilst i agree betting flush draws aggressivley is profitable im not sure about getting a 100bb stack all in on the flop against a similar stack. I wont put all my money in on a paired board as i could be drawing dead but any other time i will, even knowing that im against a set or tptk. What do others think about this practice as i get berated by players when i stack them on the river by pushing with my draw.
