[Rushmore]

I honestly think it comes from a generally greater overall confidence in skilled players' preflop, flop, and turn play.

In other words, many 2+2 types have gained so much confidence in their play on these streets (either justifiably or not), that the value bet on the river is now reasonably recognized as a rich source for the betterment of one's hourly win rate.

It used to be "become a consistent, winning player."

Now it's "maximize your win rate."

This is a good and healthy evolution.

Great thread.
