I do play tourneys, And for the typical mindset of tourneys today, TAG is certainly the way to start a tourney. So yes, perhaps I was being too tight. Funny tho, once things settled down, when I made the big bet, NO ONE CALLED. Till that last hand....
At other times, and with success, I would take hands to showdown with the feeling that I wanted to be loose, and seen as loose, and if the pot was small, I would go into these wanting to look stupid. Does nothing for the stats, but can do wonders for the meta game.
Stats are stats, I have always marveled at how 25% can equal 33%, all because of a Point of View.
I do keep an eye on my stats but mainly to see if I am playing too loose.
