Why would anyone want to work on their bullet chess?
so that when i m playing rapid with my 2000 elo opponents i m quick when i have low time
This is a misconception imo, being really low on time in a longer game is not at all similar to playing a bullet game because the game momentum has been completely different.
A year ago I wasn't particularly memorable on the forums, probably because I was so flaky and never stuck up for my opinions.
