KJs vs LP mcTAG opener

The biggest reason for me to 3bet here is to iso and not be squeezed. There are more reasons to 3bet marginal hands otb as opposed to from the blinds.

I think the squeeze comment is valid, however I'm not sure about the iso part. You want to isolate the TAG with your raise, yes? But we've already said that if he's calling your 3bet it's with JJ+ and maybe AK/AQ. How does KJs hold up against this range? I'd much rather 3bet with 54s-98s here.
