ATs against a LAG

[Alexthegreat]

There is some bad advice from some people on this thread regarding the river....Hero doesn't beat a worse ten.

I don't see much in 3-betting the river....What is he calling with on the turn that he is check raising on the river??
He must think you are just trying to take the pot away on the turn if he is raising with a 9 or PP, but wouldn't he rather 3-bet the turn and try to end the hand??

Or lead the river so you don't check it down??

Obviously you can answer these questions much better than I can,

but if he is paying attention and doesn't suck bad, (maybe this is a stretch) I just call the river raise
