My elso is around 700. I usually play Rapid 15/10 and Daily 3-day formats. I've NEVER played Bullet, Blitz and Fischer Random/960. Would you reccomend any of them? If yes, how much of my chess time should I dedicate to it? Currently, I spend: Rapid --------> 70% Daily --------> 20% Puzzle ------> 10% Thanks! 🙏
