Villian and Hero have 100bb effective stacks @100NL or smaller stakes.
Villian's stats are (12 +/-3 vp$P, and 6 +/-2 PFR, and total agg of 2.5 over 500 hands)
Despite the stats, hero is a moron, doesn't take notes often enough, and therefore doesn't have a known history with this opponent.

Hero raises in MP with QQ, the Button calls. Flop is AJ7 (or thereabouts). The flop might have two suited, but is not monotone. (pot 9.5bb)

My standard play would be to cbet here... against some opponents (those with <25% Fold to Cbet maybe) I might check for pot control, but generally I'll just stick in 3/4PSB (+7bb) (remarks appreciated if any feel the need to comment on just this).

Opponent then raises 3x Hero's bet making the pot nearly 40bb... so it's 14bb to Hero and the pot would be 54bb if Hero calls... (i'm completely out of coffee today and so math corrections are appreciated...). Villain has 75bb behind after his raise.

I'm assuming this should be a fold almost all the time, due in part to fact that this is not a standard place for this Villain to get aggressive with less than TPGK, against this hero... also in part because of stack /pot sizes there aren't enough turn cards that help our Hero enough to make the likely outcome (all-in on the turn), +EV. (i could be WAY off-base here... feel free to flame at will)

Assuming most (or some) of what I said is true... what (if anything) should we note about this opponent for use in future hands...
