Re: Look him up?
 

If it's a bluff 1 in 10 you're breaking even. He may have slowplayed a set to keep MP1 in, but I think you're good here enough to call. The BD flush seems unlikely--what did he have on the flop? A small straight?--maybe.

fold...no way are you ahead of your opponent

Would a rock take the chance of being behind on this river?

Re: Look him up?
 

What hands do I possibly have beat besides a pure bluff?

Re: Look him up?
 

I would probably call, hoping to see a worse ace BB waited until the river to raise with or a desperation checkraise from Q [img]/images/graemlins/diamond.gif[/img] J [img]/images/graemlins/diamond.gif[/img] or 66 or something.

Chances are, though, he's got 44 or 33 or 6 [img]/images/graemlins/heart.gif[/img] 5 [img]/images/graemlins/heart.gif[/img] or A [img]/images/graemlins/club.gif[/img] 4 [img]/images/graemlins/club.gif[/img] or some other hand that beats you instead.

Check this river to induce a bluff or save a bet.

Hero is last to act so inducing a bluff will be a little tough and checking the river through is seeing monsters.
