These are great flops (assuming they are rainbow)! The second flop is just very-good if it's two tone.
-- VERY GOOD
If you're heads up, meaning only one caller pre-flop, you should c-bet these boards 90% of the time or more
. It's very hard for a caller to have hit these flops strongly. They'll often just give up to a c-bet. They won't always give up, especially if they know these boards are just as hard for you to hit, but they'll fold these flops way more often than many other flops.
Also, these boards are often excellent for a turn c-bet for the times you get called on the flop and you're in position. Any card Jack or higher is excellent to fire another bet on if it gets checked to you. It's just very hard for a high turn card to help their range (once they call the flop), but those cards all improve your range. They'll fold a lot. Sometimes, they will check/fold so often that you feel like they just have
to be trapping you this time. . . but you'll bet anyway and they'll fold.
Once in a while, you'll get called down here by someone getting sticky with top-pair, second pair, or a pair like
that just wouldn't fold. You'll feel like a moron when that happens. But, if you go back and check, you'll make enough from those times they fold to compensate for these rare call downs.
Obviously, c-bet slightly more often when you're in position and check-fold more often when out of position. You also need to have a decent read on your opponent. You don't want someone who is aggressive and tricky (rare at the micros), who is willing to bluff-raise you on boards like these. I wouldn't worry about someone being that type until they've shown they'll raise these types of boards often
. Until they prove to me their aggressive like that, I'm going to c-bet because it's just burning money to not take advantage.
