Strategy:

 

Queens are valuable too worth 4 points each.

When the Tarock deck is properly counted it is worth 70 points, divided by 12 tricks per game, equals about 6 points per trick on average.

Because at least one player is going to be bleeding Tarocks, there are going to be 3 or 4 tricks in each game worth only 1 1/3 points (which is the actual value of a trick that contains 4 normal Tarocks).

This means there will be 3 or 4 other tricks worth 10 or more points; these are the tricks you want to win!
