While this thread was originally prepared primarily for PT2, with the emergence of PT3 it should be included.
As of this post PT3 has actually gone back into beta after its first commercial release. I have beta12 running, and it seems quick and pretty stable.
I am primarily a tourney player. So I can not speak about multi-tabling ring games. The folks who developed Poker Tracker have shown a tendency to prefer ring over tourney during the beta period, so this might hold true for ring game play. I follow the forums at PT and the gripes have slowed considerably since beta 12 came out. I expect either build 3 or beta 13 in mid June, but have no reason to expect that other than personal observation.
This product is damn close to being indispensable.
For a tourney player at this point I have found that the most important thing to me is tracking my money. PT is doing a great job, still needs refinement, but I have improved my game via a much better understanding, and with more control, of
bankroll Management. I know when I'm stretching it, and when I'm not.
The HUD, which is built in to PT3 is functional. Up until beta12 it was flaky, with many problems. Most of those are solved. Again, there will be more refinements with each improved release, but it is very useful as is.
Currently they are supporting 6 online
poker sites or networks. With any new release they will be adding sites/networks.
I can't imagine not having it now. I resisted it, or any poker program for a long long time. Boy what a personal blunder that was!
There will be a 2 month trial period after it goes back to commercial release. In the mean time you can use it in its current unlimited beta stage.
If I had to choose between PT3 and HoH (Harrington on HoldEm) I'd go insane as to which offers the better value.......
EDIT add for Richard;
experiment with PT3 and in particular with the
filters. Once you have chosen any particular filter, like games played since xx/xx/xx or size of buy-in, or site or whatever, then when you hit the graph tab
it will be a graph of that filtered data. Remember to
clear your filters as a routine move. You can save particular filters if you find they are extra useful. The filters will likely be the most important thing PT3 has to offer.
At the top of the PT site there is a banner for a StoxPoker video giving a pretty good overview of both what PT3 can do and how it might be used and configured. At this point that video is free. I think perhaps it may always be free, but have no proof of that assumption. I know Stox does coaching, and charges for it. But this may be a case of that video providing so much relief to the PT folks that they are paying for it. Again, speculation.
