Stop giving pieces away.
Blunders
and how to stop them
50
You blundered your queen on move nine. It happens to everyone.

You don't lose to brilliant moves.

You lose to the knight you left hanging. To the defender you moved away. To the check you never looked at.

Most games below master level are not won. They are given away, one piece at a time. Stop doing that and your results change, even if you learn nothing else.

Fifty mistakes. One page each.

Every page works the same way: what you did, why you did it, the position on the board, and the fix in one line.

Hanging pieces

The free pawn that was never free. The defender you moved. The queen a knight could reach.

10 blunders

Opening traps

Early queens, late castling, the fork on f7, moving one piece twice.

10 blunders

Tactics you miss

Forks, pins, skewers, discovered attacks, back-rank mates, the in-between move.

10 blunders

The middlegame

Attacking without enough pieces, wrong trades, no plan after the opening.

10 blunders

Endgame and nerves

A lazy king, stalemate when you are winning, playing on tilt after a mistake.

10 blunders

Read it in a minute.

No long theory. Each fix is a sentence you can repeat to yourself at the board.

Moving a defender away
Why it happens
You look at the piece you want to move, not at the piece it was protecting.
The fix
Before you move, ask: what does this piece guard right now?

What you get.
