2 pot sized bets in this spot is like 42bb so getting 50bb in really isn't much difference so I assume you'd be betting much smaller for your 2 streets of value?
That's right. 1/2 to 3/4 pot-sized bets, usually around 2/3 pot. Though I'm willing to call pot-sized bets depending on the villian, especially over aggressive types that will be looking to bluff me off what they believe to be KK, KQ or JJ.
Again, imo, cBetting a fairly dry flop with TPTK usually results in:
- winning a small pot because your opponent folds
- getting 1 street of value against Qx, pp, or Ax hands you beat, and occationally getting a 2nd street of value from Ax (though definitely not pot-sized bets)
- stacking a fishy player with a weaker A
- losing a big pot to non-fish players
Using a delayed cBet or calling in position on the turn allows you to:
- get to showdown more often with what is usually the best hand
- extract 2 streets of value against Qx, pp, Ax hands we beat, broadway hands, and random bluffs from our opponent, since we showed weakness on the flop
- minimize losses in hands where we are way behind (AQ, A3s, 33, etc)
Again, I say I rarely cBet this flop, though I will occasionally to balance my cBetting range. If I always check with showdown value and cBet when I miss, that's obviously exploitable.
I just think that in this kind of a TPTK situation, you're better off in the long run extracting value through check-calling turn/river, or betting for value IP on the turn/river, than you are cBetting the flop.
