This would DRASTICALLY increase the number of players playing variants.
I played on lichess for months before I even realized variants existed. And before that; I never even knew ANY chess variant existed.
I'm sure a lot of other people are exactly the same way. They know about chess. Thats it.
Currently, On Quick Pairings you've got 2 Classic, 5 Blitz, and 1 Bullet.
Crazyhouse for example is every bit as popular on Lichess as Bullet. No reason to have 5 different types of blitz that are all basically the same thing. Throw a ZH in there. Or throw a Play Variant in there and it creates a game with a random variant.
Or; get rid of 4 of the Blitzs and 1 of the Classics and add all the variants. That would be the best case scenario. But, I'll take what I can get.
After playing Crazyhouse I'm convinced that this is the way God intended chess to be played.
Three Check is fun too.
Racing Kings has its merits and despite popular opinion has a lot of strategy to it.
Antichess is the bane of my existence and I wish the creator a slow and agonizing death. That being said, a lot of people love it and it has a lot of fans. So that too!
Horde and KOTH aren't my cup of tea. I dont even like tea. But British people play here too!
Come now lichess. Open your wings and fly.
