I think you can play LAG anywhere.
Micro games gives you the odds
most times to chase straights and flushes with all the callers. It is almost like limit poker in that respect. This is where the loose players can catch people off guard with the strange straights etc.
Micro games you can sneek up on people and get them all-in since it is usually only 1-3 dollars to do so. They are not risking alot so they are much looser in their calls. You do this 3 tabling you can still make a decent profit per hour without much risk.
