I say reraising AA is higher variance b/c you are more likely to get involved in a very large pot than if you just flat-call. If we flat call, we're going to raise most c-bets and bet most flops when checked to, and that will usually result in a fold and a smaller pot. Most of the time we will make more chips this way. If we reraise pf we will mostly win fewer chips but occasionally win way more chips.

Yeh, well I guess reraising is always higher variance. That comment makes more sense with AQ, JJ, 98s or something. With AA, you increase your variance, but also increase your expectation considerably.

When the guy 4x it, particularly early with deep money, he often has a big ace or medium pp. So if you reraise, his action is waited towards calling or 4-betting rather than folding. Also, it is unlikely someone else will reraise here if you call. So this is just a bad situation to flat call and trap with aces.
