River bet - AK unimproved

[Entity]

Postflop is perfect. Preflop is something I've experimented with but do it more as a "gear" in HU matches or in situations where I feel my edge will -- temporarily or otherwise -- be maximized by calling preflop.

I play against the same opponents on a regular basis, and by occasionally showing AK,AQ,AA,etc, in this situations, I earn a little more validity to my checkraises with lesser hands (it seems).
