Low stakes, 100BB eff

We raise OTB with a low PP, mediocre but non-retarded TAG calls from BB.

Flop comes K73r (or similar) and he checks to us.


Do we bet or check behind?

I've been observing myself playing and I've noticed I check it down a lot. Problem is with this is it's extremely exploitable (my range for checking behind is basically low PPs and sometimes A hi) by anyone observant and that balancing it by checking behind a larger range would probably leave big holes in my game.

Thing is, if he calls we've probably got 2 outs.


What do you guys reckon?
