Four to the nut flush

[Spikelad]

What do you guys think is the correct strategy when you flop four to an ace high flush.In a cash game i usually go all-in with this hand and take my chances. My mate reckons over a period of time this is a losing play and i would like to hear your thoughts on this.

Re: Four to the nut flush Assuming your opponent has never flopped a flush or has any of your flush outs you will improve to by the river around 35% of the time so yes it is a losing play as a general rule
