I read your "About Me", you have the right attitude, your second from the last line in this post, "Maybe this is more of a concentration thing, is right on! It will improve, it happens to many players that may not want to admit it, but remember losing a game because of a huge blunder is not as bad as losing because you are totally being out played! Think about it? You will improve, if you keep playing, and as a diamond, you are too serious not to!!!!!!!!!!!!
Thought you might like this example, one way I often give a piece away is my opponent just moved a piece and is attacking say my queen, and I see it but then I look at several counter moves that may give me some decisive play, so my brain is thinking more moves ahead and forgeting a simple basic move like do something with your queen. LOLO
How in the world does one cease to make blunders in the Wonderful World of Chess? I have a bad oversight problem that appears to be chronic in nature. I will be playing a really good game then "POW" I move my Queen in front of the opponents pawn or some ridiculous thing like that. I study tactics and strategy and have fair knowledge base for my rating of BB (Blundering Beginner). I think I get tunnel vision and can't see the forest for the trees. Sure, I have tried taking more time before moving but this isn't working. Maybe this is more of a concentration thing that will improve with time. Anybody out there with a recipe for success?
