[invisibleleadsoup]

villain only just got moved to my table so no reads,but he has 300k in cashes on thepokerdb.com so i presume he's decent.

blinds 750/1500,i have 75k,he has 60k.

folded to him in mid-late position,he makes it 4k.he's been raising quite a lot since he sat down.

folded to me in SB,i make it 10500 with AKs,he calls.

flop AQ5 with a flush draw,i bet out 12500,he minraises,action on me...
