Puzzle #376 solution:
Game Svoboda – Cech, TCh-CZE 1 Liga Zapad 2017. This week's best answers are by the top scorers; however the analysis could have been a bit deeper, extending beyond simply winning white's Queen:
a) The opening is French Defence, Winawer variation
b) Black has the advantage because:
- Black's King is safe, while the white one is not
- Black dominates the center and has one passed pawn there
- Black is attacking white's King
- Three white pieces (Bc1, Bf1 and Rh1) have not moved and do little to nothing; practically white is playing down three pieces
c) Solution:
