Nope, even 3-way at 10nl I don't think going all in with AQ will be ev+.

I would have just flatted the 3bet than 4betting. Never expecting to see worse than AK (even 3-way).

This is something I've mentioned before. Especially at anonymous tables. AQs is extremely strong 3 handed, but the thing we have to think about is how much our opponents 'get it in preflop range' changes as we go 3 handed at NL10. Many opponents don't actually adapt that much. Some do of course and that's ok but I don't think we see much change in general. I'd have called the 3 bet and gone from there.

Yeh I think this needs to just be a flat call pre especially if you are confused with what to do when facing a shove.

I agree with the others, maybe at nl600 or wherever it might be a shove for the mighty JonVIP with image/reads or whatever, but here I like to call the 3bet and play a bit of poker.
@Grocker6 makes a good point about ranges not changing significantly as the seat numbers do, most people just aren't thinking on that level.

This is a great spot to defend by calling in position versus a likely wide range we dominate a lot.

One of the reasons pre flop play is reasonably simple compared to mid stakes is that you only really need to keep fully on top of whether or not villain is stacking KK+ or QQ+, AK and adjust your 4/5 bet range accordingly. As you move past 100NL when sometimes stacking TT+ AQ for 100bb becomes normal in quite a few spots it really gets murky. You very rarely find yourself in those spots at 10NL.
