Why Negreanu would even refer to AQ in the same class as 27 handwise is beyond me. First off AQ is certianly better, and I will bet anyone that 2,7 has not lost him 2.7 million dollars . Sure there are hands that are better than AQ to start, but my own experience tells me that it is much better for me to raise with this hand than call with it.
I don't know the exact numbers as far as how many times I have won raising vs calling with this hand, but I can say with surity that I have done much better by raising with this hand than simply calling.
I won't say I win everytime I raise with this because I don't, but my bankroll at one poker site
didn't go from 5 dollars to 494 by simply calling with AQ I will tell you that much.
