1. Sit on your hands when playing a game. (Except for rapid transit)
2. Write a : Before I Make A Move List (check it 2x before making a move)
If you would like to know more please let me know.
If you are under 2000 USCF or FIDE do not play rapid transit. it is bad for your game
I think more than anything it is carelessness. Ususally the fork or threatening move is only one or two moves away but in my analysis of moves I miss it. Maybe its my peripheral vision lacking. I am not taking in all the opposition pieces across the board and what threats they present. Maybe I need to systematically look at all pieces each move to see what threats and opportunities they present.
What practices do you adopt to reduce the incidents of blunders?
In a lot of games I play well for 40 or so moves then completely miss an obvious fork, pin or other tactic. Then the game is lost after playing ok.
