I get bored playing slower formats and I feel like I’m just wasting time staring at a board for 10 or so minutes. Rapid is fine in person but blitz and bullet is best for online play
Bullet: I can move faster than you, so I win. Blitz: I can think faster than you, so I win. Classical: I can think deeper than you, so I win. Correspondence: I need less sleep than you, so I win.
The only real chess is rapid and slower formats! I do play blitz and bullet but I only do to keep my rating in check.
