What you blunder

After having the site review a game of mine I see that all of my mistakes were about pawns.  Something like you missed an opportunity to win a pawn. Or your move allowed your opponent a chance to win a pawn.

At my level the winning or losing is usually failing to protect the king or blundering a piece.

So you can judge how good you are based on what level of blunder you make.....

Just a random thought about how one should judge one's chess progress.

All levels make the same blunders, it's mainly how common they are that determines your skill. A beginner might hang a piece in the first 5 moves, but an intermediate/advanced player might hang a piece every 5 - 10 games.

A noob playing a move that will lose a pawn might get a "mistake" at worst, unless it severely alters the game (e.g weakening the king) or it's the endgame, where pawns matter a lot more. Personally, I've had quite a few games where an opponent accidentally giving away a pawn was a blunder, but it was mainly because the pawn in question was a valuable defender of the king.

However, when titled players battle it out, a loss of a pawn is almost always considered a blunder, even if the win requires a series of moves that no normal human would be able to see.

Sensi, I disagree. I do not consider giving up a pawn a blunder. Losing pawns in low level games don't matter because they make tons of bigger blunders.

When you reach the level of considering pawn blunders you are quite a highly rated player compared to the general population.
