How to prevent blunders ?

I wish I had read that before I lost my last game, would've saved me my bishop...

Immediately after I hit the submit button but before the page has had time to refresh.  It's just like that moment you release the car door and realize that the keys are inside as it swings shut but before it's actually latched.

I'm convinced that somehow there's a part of my subconscious that's conspired to keep me in the dark about my obvious blunder until immediately after that point-of-no-return moment in both cases.

the right thing u will do,...u should play and play..ahmmm and kept calm,open minded that was my master says 2 me..before u will start playing u eat first,sleep (like sleeping beauty)and relax..after that ready to fight!!!ya!1i promise u it can help try... 

Tactical blindness is the main problem, and you just need to spend some time at tactics trainer.  

These checklists give you the right ideas to have in mind, but in a real game you don't want to be running through a mental list everytime it's your move.  You have to find a way to make the awareness automatic.  

I just have to quit giving the game away!! Like a probably won endgame where my opponent pushes a pawn and attaks my rook..I look right at it, and push a pawn!..unbelievable, I mean there were only 8 or 9 pieces left!! anyway I left 7 or 8 really well played games in the crapper this way...don't know just gotta look again and again I guess...maybe sometimes I just play too fast, but it feels natural..LIVE AND LEARN??..hope I'm not too old...   8-D

Lasker got it right when he said a game of chess is won by the player who made the penultimate mistake - bloody simple really

 that is wonderful

thanks for the correction, tony, I bin misattributin' that quote for years 

Everyone seems to have different checklists of things they look for before moving. That's great in turn based, but do you have time for that in blitz?

I like the recommendation from Dan Heisman: Look for checks, captures, and threats. Just scan the board for all pieces, and see what will be there after the move you're considering making.

And the only way you're going to get used to implementing something like this on every move in your games is practice, practice, practice.

Most beginners think that reading books will make them better chess players. But improvement is a combination of theory (books) and practice (games played). And the lower level you are, the more practice you need. For beginners, I'd say you should spend 80% of your chess time playing, and only 20% studying. At master level, it's probably the other way around (80% studying).

The point is that the only way you'll stop blundering is by making LOTS and LOTS of blunders - until you eventually get in the habit of looking for those particular moves before they happen. We're talking tens of thousands of real time games, not just a few hundred turn based games.
