I was a weird kid and taught myself the rules to a ton of card games as a kid, including bridge. (Except I was an only child who lived out in the country and never really had anyone to play with. Again, weird kid.) The problem is that knowing the rules of bridge don’t really translate into understanding the intricacies of the bidding strategy, and I’ve never found anyone else who wanted to learn it (my wife has, understandably, never been particularly receptive to picking it up). And it’s not like there are other millennial couples out there eager to learn bridge, lol.
I’m trying to make the canasta renaissance happen. It works well as a two- or four-hand game, and it’s social while also demanding some skill in the play. Bezique is another favorite.
