I actually thought about putting a little piece of paper on my screen to cover the hands I am getting dealt. Then just play a tournament or sit&go blindly, only analyzing what the others do and reacting accordingly. You will most likely lose, but it's maybe a good way to improve your strategic game and the ability to read your opponents.
Wow! I think, most likely it is. I'm going to try it out with some free rolls or very small stakes. It reminds me of this training for runners when they are wearing ankle weights and are running as usual, or even competing with other runners. Yes, under these circumstances, they lose even to those who are not athletes. But later, after taking the weighs off, they feel like they can fly.
