I agree that the RESULT of a 2/3 bet at my level can be hit or miss.

But from my end, if I take down the pot 2 times out of 3 with a 2/3 bet, that is my goal. I'm not putting any more money into a pot usually if I have QQ and the board has a K or A.

I also understand that I sound like a robot in this post--trying to bet exactly 2/3 and making 'standard' plays. It's never that simple, and play would depend on my read of the table and the players.

I appreciate your comments.

I think that my point was that I sometimes will bet 3/4 or even the full pot with less than top pair to try to take it down. Sometimes this is the 'right' move anyway, but this post was my realization that the bigger the bet, the more successful you have to be.

If you bet 3/4 of the pot and get called 50% of the time, you're going to HAVE to outplay your opponent on the turn and river or accept that you're losing money.

If you're following up a preflop raise with a flop bet, AND know that you'll have to check/fold if you're called (and don't improve), consider betting 2/3 the pot, as this seems to be the EV move in the long run.
