I think poker tracker for me is an absolute must - for multitabling low level cash games. It is great for 2 things:
1) Plugging leaks in your own game
2) Having live information on your opponents during a hand
I prefer PokerOffice for tournaments, but its utility is far less.
You cant use PT yet on Boss (on
Paradise it's not the best system, having to utilise email) - but the new hand historues should be totally PT compatible, so it's only a matter of time.....
There is a danger of getting bogged down in insignificant details, but so long as you're aware of that and only looking for the major things (and significant - ie with enough hand histories), you should be ok.....
Does it take up a lot of my time? No!! BUT it should!!!! I largely just let it run and use it live, with a few minutes data mining here and there - I SHOULD be spending more time with it and looking at the data in more depth.....
I think you'd be surprised how much you learn about your own game by using it!!!! I think youd find some surprises - situations or hands that you think are profitable, but aren't (and vice versia!!)
Should also make it significantly easier to see your opponents weaknesses!!! For example, you can very quickly look at all the situations your opponents is on the button and shows down AA, and replay the hands .... seeing them grouped together like that makes it far easier to find weaknesses/trends/tells
