General Theory - KK/QQ on Ace high flop

[Delphi]

Against one opponent I always c-bet here. My c-bets are at least 3/4 pot. Haven't really analysed, but I believe its EV+.

Your C-Bets are too weak. With 11 into an 18 pot or 12,5 into 21 I would probably raise you with air but at least call and float.

What would you bet if the flop was J high? Gotta be consistent and not show weakness. Make it 15 into 18 and 18 into 21 and people fold.
