This was a good read.
The "3bet/ship preflop?" part reminded me of one of the recentish threads. I can't remember who said it but the core was this:

Like mpethy pointed out, it's better to keep villain's range wider than KK+. After all, when we hold KK there are 6 possible combos of AA but only 1 of KK left. The difference between player archetypes is that nits are afraid of running into aces, and good players are afraid of scaring away everything except aces. To an observer, the preflop lines these players take may even look identical.
