PL 25 （200bb deep）
I open with AT56 double suited at cutoff.
A relatively loose player threebet at SB. I call.
Flop A J 7 , I get a pair and nuts flush draw and back door flush draw.
Sb cbet about 60% pot, I raise a pot, he calls.(His flop cbet is 67%)
Turn card is a 2. I get double flush draw. SB donk all in, I snap call.
He shows AJQ9 single suited, top two pair and Q high flush draw (better than my T high flush draw), dominates me totally.
Finally, I win the half pot lucky.

Here, I want to ash whether flop raise is a overplay. And what would you do with this hand?

Appreciate every thoughts.
