Have you ever missed something obvious that you would've spotted otherwise?
So, here's the thing. I'm in 1500s rating range and nowadays, I'm facing this "move blindness" or whatever it's called during the game. To give you an example, I was playing some games at an OTB tournament. I missed obvious threats, not even discovered attacks. Like, my opponent's queen is attacking my knight. I spot it, but I'm also calculating counter-threats. By the time I decide to move, I completely forget my hanging knight and make a random move and lose my knight.
It's not a random one-time thing. It has happened in other tournaments and online games too. I'm not even talking about blundering under time pressure. Has this happened to others in this sub? Is it a skill issue or focus issue? How do I stop this? Any help would be appreciated.
