Here's a guide to get PT3 working with Linux under wine... it took me a little while so i dont want others to go through same bother.
my version of wine is wine-1.0.1 the default ubuntu intrepid version and i'm using PT-Install-v3.00.4.pgsql.exe from the PT3 website
# Install postgresql under linux, using appropriate method
* Under Debian/Ubuntu, it would be #apt-get install postgresql postgresql-client
start the postgresql server by doing /etc/init.d/postgresql start or just restarting computer
# Create a new prosgresql user
* #su
* #su postgres
* #createuser -P genjix (-P to set a password)
* #exit & #exit (exit su, come back to normal user)
* go to http://www.postgresql.org/ftp/odbc/versions
* Choose Msi
* Choose the "good" file and Download it, in my case I chose psqlodbc_08_03_100.zip
* Unzip
* #wine msiexec /i psqlodbc.msi
now do $ wine PT-Install-v3.00.4.pgsql.exe and click next next finish
start Poker Tracker 3. when it offers to install postgresql select no and enter your username and password from earlier (in my case genjix)
it will stop at the splashscreen cos of some bug. u need to minimise the splashscreen somehow.
so on KDE i right click the titlebar or any other window -> Advanced -> Special Window Settings
click Window tab
click Detect Window Properties button and select the splashscreen
then go to Geometry tab and select the Minimised checkbox and click Force.
Now PT3 should work fine from now on
if u dont use KDE i think u can use wmctrl command line utility instead.
also when ur PT3 trial runs out u can just delete ur wine installation and clear postgresql database and reinstall PT3 so no need to ever buy it really.

If you wish to make an apple pie from scratch, you must first invent the universe.
gah i still have nightmares about linux. its safe and secure but def not worth all the trouble coz if ur not running a server why bother coz its all really a hassle and just purely for purists and hobbyists imo
