add to my previous reply above...
if we assume the button isn"t a complete idiot , look at it from his perspective if he has top 2pair or a made straight on this texture flop.You lead out and bb calls, what do you think he puts u and the bb on and with his stack size how do u think he"d continue?
This bit about "what does he put me on" is the tricky bit for me. I don"t think my image is too shabby - I folded trip jacks on the river in an earlier hand to a player who had raised the turn and led out for about half the pot on the river (he had turned the house having flopped two pair after he called utg with J8 off). Yes, I"ve been active, but I haven"t shown any real signs of utter recklessness or of crazy aggression.
So what does he put me on that is scary for his hand?
Trips? - He must know I"d have raised pre with 99/JJ/QQ so we can ignore that, can"t we?
Two pair? - which leaves me 4 outs and him as a big favourite
The K 10 to split the pot? Possible, but unlikely
A/8 10 ? possible, and maybe the only hands that makes his move make sense in a chip accrual way
or a bare 10 and fear of splitting the pot if one of the remaining 3
appears?
Is shoving in his position a good move these days ? (obviously it as for him on this occasion...)
