I used to play around 2000 Elo, but mostly switched to Go for great strategic games. Give it a try, you might well fall for it too !
Engines won chess, so how about playing Arimaa ?
I dislike opening theory, but do enjoy some fancy openings :
1… ♞f6with black (hence Alekhine and Grunfeld defenses), and vary between
1. ♙b4(Sokolsky's opening),
♘f3with white. Or some random funny pseudo-gambit.
