I'm a reasonably strong chess player, but still well blow master level (this is my lichess profile).

Nice profile. You made me reconsider "winner takes all" and/or maybe the buy-in should be smaller, lol.

Though I personally don't like correspondence games, mostly because it's too easy to cheat there (using an engine). Would be happy to play any real-time (e.g. blitz or rapid) time control.

Oh, great point! @kristapsk also expressed preference for real-time games. I would also actually like real-time games more.

Btw, did this post make you sign up for SN to reply? If so, cool and welcome!
