A9o Deep and Early

I can't think of a good line that I like on any streets here. Shoving the flop gives us little value and takes the pot down, which I don't know if thats correct. Results shown for better discussion.

*** SUMMARY ***

I like your line. Turn brought a three flush which is a scare card for you so you can't really raise turn for value, but you can't fold either. Basically, you couldn't play better. If you were up against aggressive player, I like checking the flop, because he will play his draws aggressively, there are a lot of scare cards and you are either a little ahead or way behind. But this guy isn't very aggressive and is donkish (since he minraised, I guess) so your line is standard.

Lately I just fold pre flop

I'd fold turn as played, flop/river seem good to me.
