My guess is that you are moving quickly to get away from the tension that you are feeling inside when you have to move. Breathe, relax your muscles, and tell yourself the slower you play, the better you will feel. In a good game, I can feel my heart-rate go up and learning to relax helps lower that a lot.
I'm playing too quickly
When you first log in, you could start by playing a warm up game against a bot. They move quickly so you don't have to wait for them, but there's no clock to pressure you and it's a bot so it doesn't care how long you take to make a move removing any concern that you're irritating your opponent by taking your time. Once you can get yourself into the frame of mind of working through the position before selecting your move, then take that mindset with you to your human games.
don't play when u're hyped, tired try looking trugh your oponent's movemnts and focus on winning not on quicker moves
I moved quickly and now I see a mate in two I missed.
I moved my Queen then a bishop to pin his queen instead . . .
Before I move I should take another look . . .
Happens to me when I just finish playing bullet or blitz and the start playing a rapid game
That's ok you want to play a little fast rapid games get dumb when under 3 min anyway just try to remind yourself to slow down(WITHOUT ) freaking out or accidently panicking and blundering something even tho you have thought for five minutes
A couple blitz games as a warm up wouldn't be a bad idea but instantly playing all your moves would be unhelpful unless you have a good reason
I know this sounds like a silly question... but I'm playing too quickly and not calculating enough. I know the simple answer is 'slow down and calculate' but for some reason I'm really struggling - my opponent plays a move and I feel like I need to respond instantly. Any tips for how to relax and what I should be looking for in calculations? Thanks.
