[El Diablo]

David,

As I stated in one of your threads, I agree w/ your general premise regarding who wins the most and why, and how changes in strategy affect the earn of these different types of players.

In fact, I have covered that specific point in various posts in the past in this forum when I've discussed how to exploit certain types of players who give way too much action across the board and the changes I make in my game when facing the small handful of aggressive players who do a really good job at mixing up their play.

So, big picture, I think we pretty much agree.

However, wrt this hand, I continue to disagree. That is because of the following things.

Guys in the middle will be involved with hands like K4s and will call your flop bet and get stacked when they improve to a second best on the turn. These guys will fold to your checkraise, though. In a lot of games, the range of such hands that will call that flop bet is far wider than top pair.

Aggressive PFRs will often raise you with hands like AK on the flop, but will proceed with caution after you checkraise. If the board stays friendly, you probably stack them anyway. But you can often build a bigger pot against these guys and increase your likelihood of stacking them by leading into them on the flop.

Certain turn cards on a board like this can kill your action against hands that would be willing to give a ton of action on the flop. (This point is reduced somewhat by the fact that you changed the flop to rainbow)

There are other reasons as well (including balancing reasons when considering the range of hands we're going to lead with vs. checkraise or checkfold), these are just a few.
