i come across them all the time and i just dont know. Im leaning towards a fold. May not have an ace, could have a 9 with a better kicker. Raise with a flush draw?
This could be a good slow play preflop with an A, but I think it's a steal attempt. Usually the A will raise. I come back over the top. If I want to send a message then I push, otherwise just something like 450...well, check that, you'll be pot committed. I push.
