I guess opening isn't too bad small to big but then you need to be cbetting this flop, V has air so often and when you check it to him twice he is almost always betting his entire range and you basically have to fold every no pair hands...
I think the mistake in this hand is checking the flop.
Fold pre unless villain is very tight. Nice flop to c-bet and look to give up if he comes calling and you are unimproved, saves getting into expensive spots later on in the hand
