Strategy Question for 2+2 Authors

[Depraved]

Astroglide started a great thread a few days ago questioning the rationale behind calling with QQ on the button in a multiway pot. If I interpreted David's response correctly, he said the play is optimal if you want the overpair to hold up on its own, and the specific merits stem from the increased probability someone to your immediate right will bet into you given you're not the preflop raiser.

I'm still confused over when to favor tactics that maximize your chances for winning the pot, and tactics that maximize your chances for winning the most money. What factors should I be weighing when I decide to choose one strategy over the other? Is it even worth consideration at all? Specifically in another part of HPFAP, I believe the 2+2 authors suggest cold calling a raise in the big blind with KK if the pot is multiway. The rationale is you can bet out on the flop and expect the preflop raiser to raise, thus thinning the field for you.

At least one competing author advocates capping preflop with KK/AA, with the assumption you will make the most money this way. When is this wrong? What factors determine when it is wrong?

Do you think the difference is negligible?
