Pinochle
There is a serious strategic flaw in the program. If the bid winner calls spades or diamonds as trump, his partner should always pass the queens of spades and jacks of diamonds that he has. Your program will often have the partner keep a queen of spades or jack of diamonds to complete their 60 queens or 40 jacks. That is bad playing, since the queen of diamonds or jack of diamonds in the bidders hand will most often result in higher points.
This program still has the same flaw. No doubt the programmer has never actually played pinochle with real people. There are other flaws as well.
