i think the flop check is correct (though imo it'd be a pretty comfortable c/f as we're never going to make enough $ the times we bink one of our two outs with these stack sizes). turn play is good too. you rep basically slowplayed nuts and turned nuts or maybe like AQ/QJs that checked flop for pot control. i wouldn't worry too much about what you rep at these stakes though. even the better players will be liable to making large mistakes. i mean it's definitely a good thing to be at least slightly conscious of what your range is at all times and what you rep, but vs these guys i'd look to just maximise my EV with whatever cards im holding.
