I auto queen because the scenarios where I need to queen and mate within 1 second happens more often that the scenarios where I need to underpromote to win
I have it off because I don't usually end up in time scrambles
Ah I'm a filthy flagger so can't relate
I also flag people
I have played in the 15 seconds tournaments at Lichess lately (after a break) and it is basically about premoving every move. 30 seconds tournaments here are a little bit like that too, but not as much. It's a bit crazy I know. I have played the 15 seconds games to improve my speed but it has resulted into some of the worst premove blunders here so not much help. Perhaps more helpful to practice puzzle rush 3 min. Current record 22 a couple of days ago. I know it is not even top 1000 but anyway. Practicing quick reactions to situations.
