I pretty much agree with you BBB.
I definately play more hands at the beginning of the tourney than a TAG. Later in a tourney it's important not to lose chips if you have them while at the same time build a stack (easy ) but the optimum strategy is so dependant on so many things that it's hard to generalise.
In the early stages there is a chance to play some speculative pots in late postion or wth good implied odds
, or from the blinds. The idea is to risk a few chips in order to have the chance to pick up a big pot. There is a lot to be said for taking a number of small risks in the first hour on your own terms to avoid having to take a couple of really big risks in the second and third on someone elses.
A lot of people get carried away though and fail to let go of hands post flop when they connect with a flop but not quite hard enough. If you play KT then it is not to hit a King high flop it's for two pair or better. Even worse you don't want to spend too many chips chasing draws. Essentially hit hard or get out or become the person that is being milked by the others.
It's almost a loose-passive approach early on (first 2 to 4 levels) which is paid off by the many maniacs when you do connect.
Later on this approach is absolutely not the way to go as you will bleed chips and be sussed out pretty quick in 2-way and 3-way pots when hands are much better defined by the preflop action.
