To this point I've tended to be a rock that ventures into LAgg territory about 25% of the time at a table to mix up my play, trip up opoonents, and practice tough thinking postflop play.

I'm now starting to become even more LAgg as I am comfortable outplaying 80%+ of players postflop at the low stakes games I play ($5 and $10 SNGs and MTTs).

The question is, do you sometimes get into a mindset of "well I think he has this, but he thinks that I think he has this. And he thinks I have this I think but he may be outplaying me so I think he is putting me on this range.... what's my play.... crap my head exploded"

In general when playing LAgg against fish you just play the opposite of their style and attack all weakness and leaks that player has, but when up against another thinking LAgg my mind trips up.

This is probably too long-winded so in short:
How does a thinking LAgg play against a thinking LAgg?
