I've been playing a few micro stakes multitable sngs lately and I've one spot come up a few times which I'm not sure how to deal with.

I basically try to play a fundamentally strong game and profit from other players making stupid mistakes (because it's microstakes), but occasionally I'll make a standard raise from a position where the range is appropriate, get 1-3 callers, and miss the flop. If I'm in position, they check to me, I throw out a cbet and one of them raises or even jams and I need to fold, as their range is terrible so they can flop the nuts on a 356 rainbow board. If I'm OOP I cbet and the same thing happens.

Obviously one solution to this is to stop cbetting unless I flop a hand or a decent draw, but then I'm literally playing poker where I only bet if I have a hand. Is there a way to defend against this?

Why are you cbetting with a marginal hand that cannot stand a raise in multiway. Mainly play fit or fold in this situation. You can bet your strong draws too. You are making a mistake with cbetting wide.

Also strongly consider the flop texture when deciding what to do. On a low, connecting flop like the 356 you described, it connects better with their range than yours. Your KQ is worthless and a bet looks weak on that flop. Checking behind with overs is rarely a bad choice. If you raised button and flop comes K-7-2 rainbow vs one opponent, this is a great time to c-bet even if you bluff raised with 84o pre.

Just from your paragraph I think you migh have a fundamental misunderstanding of the c-bet. Its not a tool to be used blindly but with careful thought. First thing you that should pop in your head before c betting is how does the flop connect to my range and my oppents.

I think you might be c betting just to c bet hoping to cheaply take down pots which is why your finding yourself being exploited. Put a little more thought into why and when you c bet n you should start to improve in this area.
