I haven't played much serious chess lately due to work, but what I have done is teach bullet players over 2300 a lesson every so often, which has become my favorite mode.
One way or another, bullet is always going to surprise. It's where the winner is not only the one with the best strategies but also the one who best uses their time on the clock and the openings. They are important, the middlegame is important.
But nothing is more important than staying ahead of your opponent when we're behind on the board. The key here is to hold on when we're behind and attack as much as we can when we have the advantage.
Although I have noticed that if there is a difference of more than 200 points, we're going to have a very difficult time. This is where we can see who is stronger and who has better grasped the principles of chess.
It's a good way to practice strategy and openings, and if we want to play quick games, to understand what our opponents' first thoughts are when they face our opponents. Moves
As for the rest, I think it's part of the chess show. Bullet is by far the mode that surprises people the most when I tell them I play chess. It's hard to imagine that a game can be played in less than a minute, but here they are anyway.
