ARGH! nononononono! that doesn't help at all, I can see any two cards in his hand, so each hand has to be examined individually. Who's the villain, how does he bet pre and post, what does it mean when he does X vs past play experience. Ranges suck because they can be so wide, sure "good" players will follow a chart based on position but really bad and really good players will often play so-so starting hands and boards like above make it impossible to figure out.
I say he's (CO) got it, could be AA with 3xBB bet wanting to get some action with only 3 players behind (2 IP/ 2 OP), same can be said for JJ, QQ, KK or AK
So post flop he just calls, he made a set of A's and doesn't want to give away his strength, turn starts to look scary so he re-raises to drive off the flush and straight drawing hands or make him pay dearly to try and make them.
Or he had the T9 and made the straight, AJ is still nice top 2 pair to bet though, JJ gets scared by the A on flop but can't decide if Hero has A so just calls and like mana from heaven a J falls, and on and on. Or just maybe he's smart enough to know that T9 in the BB isn't worth calling a raise OP and the board looks scary so he bluffs, it's a great bluff look it's got a set all shook up.
