Extremely bad decisions by the computer teammate and opponents alike.
Examples:
Use of trump when the hand is won already.
Wasting trumps
Not using trumps when they should makes you assume they are out but then they start the next hand with a trump card.
Not sure if it is programming or if the developer needs to consult a few good players.
This has the potential of being a fun entertaining game.
Please fix it.
