When is it wrong to not C bet heads up in a pot?
I've been watching lots of videos about C betting and the pros give a wide range of responses on when and how to use it. Take Gavin smith for an example. He C bets 100% of the time heads up. This goes with Danny negreanu green stein and other pros. However gus says u shud c bet about 80% of the time so that it allows you to control the pot size, slow play or whatever. I'm with Gavin being the most profitable strategy is c betting 100% (obv if I put my opponent on a range that will hit the flop more often than not, or if I think he has a pocket pair I wud check unless qualified (I hate that word used in poker btw) haha.
So what do you think? Please give me advise I really need it because I think this is/ could be my biggest leak because it ranges from being very profitable to throwing money away.
