i would x/call on the flop. this oesd is not very good, it does not have fd/bdfd and opponents have plenty Ax hands in their ranges that could block our outs.
Yes fold pre KJo is an ugly hand - as played would bet the flop but not shove ranges are pretty wide and we will often get folds. Not too worried about being raised off our draw.
Pre is fine for 6max. I would not open 3x with your stack size
Bet/fold the flop is ok, button probably is calling pretty wide pre so you have good fold equity here
U don't want stupid floats so bet around 66-90% and fold to raises
