u bet OOP to fid out where ur at? first off to find out where ur at u will have to bet a marginal amount. since there is 50 in the pot then you would have to bet around 30 and then what do u do on the turn if u r called on the flop OOP. you can just as easily check to see where youre at if your observant enough to previous hands. in this case it seems like he may have been called by aq ak maybe aj. if u raised pf and come out bettin and someone who called had aq or smaller ace then they will just call and then youve wasted your money.
