Limit 40-80 O8 Shorthanded question

[obi---one]

Great Limit 40-80 Omaha eight or better game. We are currnetly three handed and I feel I am in a great spot. This hand was a couple of days ago so I don't remember all my cards but remember the important ones.

My hand important cards k [img]/images/graemlins/heart.gif[/img] 10 [img]/images/graemlins/heart.gif[/img]

Three to the flop of j [img]/images/graemlins/heart.gif[/img] 9 [img]/images/graemlins/heart.gif[/img] and 4 [img]/images/graemlins/club.gif[/img]

!st position bets out. My thoughts are, great I have flush straight draws, and unlikely low. I may scoop. Guy in 1st position is calling station. I can't run him off his hand so I need to make something I call. Third player calls.

Nice card, I now have the nuts with redraw, with no low possible. The kind of hands you dream for in o8. Now, 1st position checks. I bet. I get raised by 3rd position, I, of course reraise, with my redraw and current nut. 3rd position knows how to play cards. I know he has top set or same hand. River is king. So Final board is k [img]/images/graemlins/club.gif[/img]q [img]/images/graemlins/diamond.gif[/img]j [img]/images/graemlins/heart.gif[/img]9 [img]/images/graemlins/heart.gif[/img]4 [img]/images/graemlins/club.gif[/img]

I check and he fires. I don't like it because he could have limped in with ak10 something and he has redrawen for nut straight. In fact, that is exactly what I think he has. Do I have to call him down on the end?
