1st post of the day, and probably under caffeinated.
I think it is unwise to think this way regarding HU. LAG vs TAG at HU have only remnant effects, as if you were sitting at a full STT table and watched your villain as the table thins to HU. You will have been exposed to his adjustments. And you can bet that all the players at that table will have made adjustments along the TAG-LAG scale, and by necessity it has to be toward LAG. But again, that is the wrong way to think about it (IMHO). The average non-paired hand in HU will be 7-8, and the average paired hand will be a pair of 7.5's, and on average one of you will have an above average hand while the other has below average.
Pure HU, where from the gitgo the game is mano e mano, is less about cards than it is about juevos. Again LAG-TAG shouldn't be the thinking. More like "My club is bigger than your club" uuh uuh.
If you approach this as a LAG TAG thing, then you will be aggressive with a 98 figuring on average villain will be holding 56 (approximations). And from a statistic POV, HU fits into a LAG fest anyway. Your vp will approach 50%, your AF will also, and theoretically your PFR should approach 100%. Very LAG, but not so appropriate for HU thinking.
If you want an easy way to think about 6max vs full ring, just remove the UTG, UTG+1, and UTG+2 starting cards from your thinking.
