Calculation Errors: The Ghost Piece
In my daily tactical training I made a calculation mistake which is very instructional (and embarassing).
Blokh Combinational Motives: Diagram 717 Difficulty 5, White to move.
Here I spotted a thematic sacrifice on f7 and a way to win two pawns.
I calculated 1. Bxf7+ Kxf7 2. Nxe5+ Qxe5 3. Bxe5 Bxe2 4. Bxe2
There was only one problem with this ... I no longer have a bishop on c4 to play Bxe2.
I call this a "Ghost Piece" ... where you lose track of the pieces on the board when calculating variations. Be on the guard against this
Can you solve?
