Preferred time control: 3 days / move. I am likely to decline invitations with longer time control.

I am also likely to decline invitations with non-random choice of sides.

I have no interest in games with luck elements (though sometimes a random starting setup is acceptable), or games with hidden information.

I generally prefer playing to a set number of wins, in order to avoid drawn matches, as I find that a boring and disappointing result. Specifically, I prefer:
1-win (or more) matches, for fair games, e.g. most chess and checkers variants, including standard chess.
2-win (or more) matches, for games where one side has an (clear but overcomeable) advantage, e.g. atomic chess.
4-game (or more, but an even number) matches, for games where one side has an usually winning advantage (e.g. Alquerque, Horde Chess). While this risks the match ending in a disappointing draw result, at least it won't give the win to a player purely due to them having the luck to get the better side first.

I also play chess variants and other games (mainly Alice Chess which sadly isn't available here) on Scheming Minds and Gold Token, using the same nick.
