I'm a major LAG

[MLG]

If you are 100% sure that he has AA/KK then you are limping purely for set value which is ok as its less than 10%. It is also possible to not go broke on an all low flop. Just play carefully, like call the flop and fold the turn if he bets twice. You are in one of two situations. Either you are 100% sure he has AA/KK in which case you are just deep enough to limp only for set value, or you fear it enough to not raise, but aren't completely sure, in which you should be playing carefully on safe flops which has some value.
