How can one cope with experiencing intense frustration or anger on losing streak in chess ?
I had a thing happening where I was getting frustrated, angry and resigning even when it turns out I was winning. So, every time I'm like "this is a terrible position, what happened?" now I remember I'm not really good at knowing if it's a terrible position or not. And then I usually find something. Or my opponent makes a mistake. Or, I eventually lose and skip the frustration and anger part. Also I highly recommend https://www.amazon.com/Defending-Under-Pressure-Managing-Chessboard/dp/1936277964 even though some of the actual games are over my head it's helping a lot.
Tiger Woods trained intensely to handle his emotions. Nobody was better than him for having a horrible hole, and then turning it around afterwards. The trick is letting it go before moving to the next game. Count to a hundred, exercise for a few minutes, whatever it takes to let the frustration go and move on.
