Blunders are horrible, destroying a well-played game. Well, you may not feel that bad if you know that the World Champion also makes blunders. Magnus Carlsen blundered a full piece in this recent game. Carlsen just played 45. Rg8?? (from b8). What should Black do? (The answer is under the board.)
To avoid these blunders, ask yourself the following questions:
1. Why did my opponent make his last move?
2. What should I play in response to that move?
3. What will my opponent play after I make my move?
Answer: 45... Ne7! The discovered attack threatens both the rook and the knight. If White tries 46. Rxg7 to capture the knight, 46... Rxd3+ wins the White knight with check. After 47. Kc4 Rd7, Black will be up a knight for a pawn.
