Hand played in London at £1/2, villain has 260 and I cover. He is an American gentleman, in his 50's and his wife is also playing at the table. He is fairly loose and has shown a river bluff to one of his friends he is drinking with. He knows nothing about me.
Two limpers and I raise on the button with A9o to 10. The blinds fold (including his wife, who jokingly says I shouldn't get in the way of a marriage dispute!) and the 2 field limpers call.
Flop (pot 33) is AJ9 with two spades (inc the Ace). I have no spades. Checked to me and I make it 20, EP folds and villain calls.
Turn (pot 73) is offsuit K: He checks, I make it 50, he thinks for a second and makes it 100. I call.
River (273) is offsuit 5: He pushes all in for 133. I think for a while and fold.
I am getting about 3-1. The only value hand I can see him having here is QT, which I think he has most of the time. I can't rally see him playing a flush draw this way or KJ because I think it looks as though I have 2 pair minimum when I call the turn check-raise. I just can't see myself being good 25% when he shoves. Also I think that the presence of his wife is a small factor against him wanting to be felted. However, thinking about it now, he could have hit a K and a flush draw on the turn, although perhaps I am just inventing hands. I know there is always a small % of bluffs in people's range but this surely would be a terrible spot to do so? Against an unknown, is this always a fold?
