Curious to find out why this is in your 4betting range - for me it plays really well as a call preflop.

As played it seems fine but I have a feeling this is going to be close the top of your checking back range? I don't want to make assumptions on how you structure your checking back ranges but I would assume that you would have bet AK etc on the flop.

If it is the case that this is the top of your range in this spot then obviously you can be exploited if you're folding this which leans me towards a sigh call.

I would propably call versus sizing, but only because i think that he might sometimes play with weaker Ax for value like this.

If he plays turn/river with bigger sizings or even use bigger sizing at river, i wouldnt mind folding. I think population is playing AK/AQ with this line just way too often there and is unbalanced towards value
9h is actually opening some bluffs he might check on flop, like T8s/T7s, but with hands like QT i think most people bluffs mostly by betting flop/turn instead of checking flop and delay cbetting.
