Its nothing to do with philosophy , its bad advice that you are giving. If you want to play loose and get into spots fine, go ahead . I'm laggy too , but this is a guy wanting to know how to beat 2nl. The easiest way is to tighten up your starting hands , play in position , set mine, fold to late street aggression and profit. He can start adding in more marginal hands once he has become profitable and starts to improve his post flop play.

Most of the 2nl spew is directly attributable to pre flop mistakes , so why advise him to make those preflop mistakes in the first place
