Overall, Hoyle isn't too bad, but I find that even on the "advanced" setting, your partner is too timid, mostly by failing to lead trump on your call or order. However, they often order up from first with 2 bowers and no support, when they could have had 3 or 4 trump by passing for "next".

Also, 1st chair never donates.

Unrealistic loners, the computer often takes trick 1 with trump or off Ace, and properly leads the Right, but then leads offsuit to give the opps a chance to stop the loner. Even when holding JJ9, AK.

Pinochle:

In viewing the meld, you gain additional information that can be used later in the gameplay. The computer never makes use of this. Say your P in double-deck has 3 aces of diamonds (which you only know after the fact) and you make diamonds trump with a run (so the computer should know you have the 4th ace). You lead the Qd. Your P should play the 10 of diamonds and lead back at least 2 ace of diamonds before playing other suits.

Also, in the bidding, if you are in a game to 3550 and both teams have around 3000, you cannot count on your P to bid even if you have no marriage yourself. This is very frustrating because you now have to bid a lot more. I think it is so the player can have the glory, but I want the computer to play with the understanding that you must bid to win.
