# Puzzle of the week #70

Level:
5-Queen
Chess Diagram:

We saw in the other puzzle what happened to the Black King placed in the corner. His blocked position was masterfully used by White in his plans to win the game. Let's try to sort out another similar situation, but put the Black King under less pressure.
This is another study by Selezniev from 1912. What I like about his puzzles is their sense of real, meaning it is very possible you could encounter such positions in your games. This makes them more valuable and speak volume about Selezniev's chess abilities.
a) Analyse the position to identify the positives and negatives for each side (10 points)
b) White to move and win (10 points)
Total available points for this puzzle is 20. The answers will be published next week together with puzzle #71.

Puzzle #69 solution:
This time I chose Andy Y positives and negatives and combined them with John's solution:
Andy Y
"Black seems to be winning this. He is up by a pawn and has two advanced passed pawns on his opponent's 3rd rank, separated by one file. The problem is that his King remains in the corner and White's Rook makes escape difficult as it controls the 7th rank. Black's Rook is also extremely passive, relegated to defend his back rank. White has a kingside pawn majority, but his f-pawn is backwards. White must land a decisive blow before Black queens a pawn."
