Very Common Chess Error

In the following 3 minute blitz game played at ICC, Schiller of Belgium playing White against an Exchange French Defense  made a mistake that has also plagued me most of my career.

Black played Queen to the e2 square offering the exchange of Queens and establishing a Rook on Whites 2nd rank. White chose to play Queen to the c4 check giving check forgetting that his unprotected Queen is still being attacked by the Black Queen.




Black acquiescing to the phenomenon  of mutual blunder moved his King! White still not noticing his mortally wounded lady, made another move. Black, on his second opportunity, finally noticed the en prise dame and captured resulting in Schiller's almost certain dejected resignation.

The type of mistake moving away from one capture square to another capture square is very prevalent and likely has a psychological cause.
