We are talking fixed limit holdem, right?

The point of betting river is not to make him fold and win the pot, it is to make him fold a better hand or call a worse. (read TOP) None of those things will happen very often if u got something little like a small pair or A-high.

Normally u should bet if u got a hopeless hand, bet if u got a good hand and checkcall if u got something little. But of course its player- and board-dependent.

Get the feeling u think u have found a nice theory to show the turncheck is a mastermove headsup. It normally isnt. When u move up in limits u will play more and more aggressive player and then your turncheck will give u problem on the turn, not give u a chance to bluff river.
