Bluffing on a monochrome board

Why are you cbetting here? You are multi-way, and with a monotone board like this you probably should be checking most of your range, including most flushes to balance it. When you do cbet it usually should be small, about 1/3 pot. Bigger sizes tend to fold out most of villains marginal hands that you would want to continue if you had made a flush. A Simce you want to bet your value hands small, you should use the same sizing for bluffs.

Having cbet, why in the world are you calling the flop c/r. Even if it’s a bluff you might be behind, and your hand hs essentially zero equity. The only way you can win this pot is a successful bluff. Villains at micros won’t typically c/r monotone flops then fold to a bluff; he very likely hit a flush, or at worst has something like AhX as a c/r bluff (if he is an advanced enough player to worry about balancing his c/r range with bluffs). If he has a flush he isn’t folding. If he was bluffing with a flush draw, it hit.

Nothing wrong with simply folding a nothing hand to the c/r. BTW nothing wrong with folding that hand PF at this level either. You already have two limpers and the blinds still to act. What is your plan if one of the blinds 3 bets or if one of the limpers does? If you really must play this hand, an overlimp might be ok too PF.
