Negative variance has been kicking in for me like something fierce for the last 2.5k hands or so at 25nl on party and its causing me to second guess my strategy.

I think one of my biggest chip spews is coming from C-Bets. I am running a VPIP of about 15%, so It isn't that I have a loose image or anything. My C-Bets just aren't getting respect at all. So every time I have AK, and flop comes something like 9.77 and I fire out a bet, they call me or reraise all in practically every time. So thats like 10-20 BB down the drain every time.

I wanted to hear from some other players who have experienced success at this level. What is your technique for continuation betting. Do you do it every time? Do you only do it on unscary flops? Do you vary the size of your bets at all, depending on flop tone? Does cbetting even work enough at this level to be more profitable than just throwing your hand away everytime you miss?
