Is there value to being able to play multiple styles well?

HU, my style is to try to figure out what my opponent thinks I think about what he thinks I'm trying to do and then get confused and do something completely random because the damn computer is beeping at me (and by "completely random" I wish I meant "game-theoritically optimal" but I don't) .

I think straightforward ABC TAG play will make money up to 2/4 6-max on Party skins. It isn't optimal, but its breakeven at worst (I believe TWP has said this before as well).

The concept of changing styles doesn't really apply at the higher levels in my opinion as the game is constantly evolving. When everybody at the table already knows the "by the book" line, deviating from it is just a mind game of zigging when they think you're zagging. It isn't about saying "For the next half hour, I will be a LAG, then I will be a TAG for 20 minutes, then I will be a rock for 10, then a LAG for 15,......" as those labels don't apply as strictly as they do at low levels where most players always play the same way.

The bottom line is that you only need to change styles when other people start changing them, too. If everyone at the table always plays one way, you play a strategy that counters that one way. If they change, you change too.
