I would love a Wikipedia list article of games that have been solved computationally and but also games where humans can still beat computers / AI, discussing the challenges and context behinds wins / losses.
I couldn't imagine any computer beating a human at any Collectable Card Game in the near term. Likewise I'd imagine that computers would be at a insurmountable disadvantage at Deck Builders like Dominion in the general case (in that I could easily imagine a Computer being trained to play perfectly on a specific Kingdom but no where close to a top human on a randomly selected Kingdom).
AFAIK there are no good bridge computer programs. A crucial difficulty is making sense of the bidding phase, and of signals during the card playing phase.

Not being on that list doesn’t necessarily make a game harder; it may just be less popular with computer scientists.
