just keep your time higher than the other person's
It has been a very long time I basically quit chess and remember I made this forum
play on 10sec and just give checks its that easy
also i recommend playing on mouse as it helps with speed if u get used to it (if you already do then great).
I play bullet once in a while, but I have to wear headphones (on my PC) so I can hear the other guy move so I can react right away, lol.
I pre-moved in the past and now I'm playing well
For the opening I recommend you to play the Ponzian opening
