I often find myself faced with an opening raise from a rock running around 7/4 while I'm holding something like AQ. While I do have the advantage of position, I really think he's way ahead of me.
Is there any method of guessing a bit more precisely his range? The best I came up with is : 4*261/100 = 10.44
So that 4% PFR roughly corresponds to the top ten hands. so TT+, AK, AQ, KQ.
Is my reasoning right?
