Most people use the computer analysis these days. The problem is that putting your games out here opens you to comments that may be less than kind.
If you do want to post your game, it helps if you use the Game Editor tool. It looks like a little chessboard in the text edit box. Nobody wants to read a whole pgn without diagrams.
You would typically try to analyze them yourself and ask for help on something you may not understand. Doing the analysis yourself first is really the only way to get better.
Just posting a game without making any comments yourself typically gets no help.
I have posted one of your recent "wins" above. You were doing pretty well up until move 21, when you sent your knight behind enemy lines to attack a rook. That was a bad move. If the rook had simply moved to attack your knight, you would have no way for it to escape.
You also put your rook in a place to get captured by a pawn on move 24. Perhaps that happened because you were getting low on time.
Do you remember what you were thinking?
It looks like you would have lost on time if your opponent hadn't abandoned the game at the end. You had only 27 seconds left and you were taking about 30 seconds per move. Do you often lose on time?
You are a premium member. You can get computerized analysis of your games for free. Just click the link to "Computer Analysis" after a game. It would have pointed out the major blunders you made in the game above and suggested better moves for you.
how do I have my games reviewed by people here on Chess.com?
