sorry, vague answer coming.......it could be.

honestly, there isnt enough info there to be sure one way or the other. not that you didnt give some good info there...it just isnt detailed enough because you cant cover every scenario with generalities, and i finally see what the "old dogs" here talk about when they say....it REALLY depends.

one thing i do see, though. i wouldnt bet less than half the pot on any flop. i would keep it to more like 2/3 to 3/4. less than half just encourages air to minraise you, imo.

you are having a lot of the same problems i have from time to time.

- you sound like you are getting a bit "stack happy." where you want all of your opponent's chips everytime you hit a flop. that just cant be done. its one of the main reasons i went on the previously mentioned 12 BI in 10 day downswing. i was pushing everything too hard.

- sounds like you are "peppering" pots so frequently that you are only getting played back at with the goods. and, that only spurs you on because you are sick and tired ot only grabbing the small pots with flop bets.

if so, scale back on your cbet frequencies. not forever, for awhile. start calling a bit, or God forbid, fold a flop when you whiff. experiment with "floating," meaning wait for the turn to bet/raise. see if villains start to give up. stop double barreling so much if you are doing that frequently. maybe a check/raise when you hit a flop and are sure your villains are sensing weakness from you because you bet so often. throw 'em off by mixing up your play a bit. dont take it too far, though. when you bet EVERY flop you raised pf, you get very exploitable by anyone with a brain cell left. and, it can feel like the world is just picking on you.

it could be that your stars are no longer "lining up" and villains HAVE the cards they are advertising...again, variance. but, it could also be over aggression. hard to tell.

and, yes, dont EVER underestimate the value of note taking...at any level.
