Committing preflop based on note

In this hand i'm up against an opponent on which i have following note : shark, but overplays AK and/or medium pair early stages

With this in mind we elect to put a serious 7X 3-bet in when raised to us , instead of the usual 3X 3-bet.

Why ? Various reasons :

1. Because we want to commit villain preflop and the normal 3-bet just doesn't do this. Pot would only be 900 preflop with me having 2.1K behind and villain 3K. i would need to bet every street and get called every street to get it allin with these stacks. I want to get it allin on 1 street or pre( ofc in this hand the flop came just to good to put it in on flop )

2. Because doubling up here means i have 5K leaving all others behind with 1.5K making me strong favourite to win.

3. Because of the note

4. Because many weak players play small pairs/ AK the way i play my AA here , they raise very big pre because they don't know how to play a flop , so they want to get it in pre or just take the pot pre. Villain being a good player may pick up on this and will hopefully not put me on AA with this kind of big reraise.

It called mixing your game up.

Flop came just perfect, river got me scared a little lol. Took the big pot, took the lead and took first place.

Cheers.
