NL400 AJs

Think he gonna look you up way too much for a jam to work there. I assume that he thinks youll play your 2pair/sets faster and you shouldn't have clubs here (maybe just 45cc and 56cc). Sometimes u might even be good here so yeah I'm cb here.

I think if he folds the river you had the best hand. Doubt he ever folds better.

I would be surprised if he checked river with a value hand.

yh gotta go with everyone else here, his turn bet is kinda weird for a river check, really feels like he would bet a little more without AK/AQ which kinda makes me feel that there is a chance you might see him show up with a weak A* he's 3b from the blinds (A3s etc) but most likely you're just going to check and win here.

It's ofc possible that he's checked the river with AK/AQ, if he has though, he has almost certainly checked to chk/call - unless there is something about your perceived image you've not shared.

Having said this, jamming is good for the NSD line ♦

I like preflop.
Given our image we can not get him to fold his equity if we shove, so that's not an option (probably even AQ calls).
If we 4bet he'd need to 5betbluff a ton to make a 4bet/call profitable since he's probably getting it in with 99+,AQ+ for value.

At the same time even vs a 9% topheavy range we have 46% while we only need ~33% to call.
