Continuing along the same line of revisiting games of great chess wizards, let's stop this time at the above position! The player handling White at the time (back in 1963) was none other than Bobby Fischer and the game is part of a simultaneous exhibition. It is Black's turn to move after Bobby has just moved very casually 13.d3 ... He thought that it would be an easy outcome to overpower Black given the exposed Kd8. Shockingly he was in for a very unpleasant surprise, as his opponent played the combination of his life. Questions:
a) Black to move and win; after the first 2 moves there are 2 possible lines based on what White decides to do. Each line is 4 moves long in total and it is worth 3 points; a complete answer here will give you 6 points in total
b) Guess the first move of the game for White and Black (1 point value)
c) Guess the opening name (3 points)

Total available points for this puzzle is 10. The answers will be published next week together with puzzle #16.

Puzzle #14 solution:
Mikhail Tal (November 9, 1936 - June 28, 1992) was a Soviet-Latvian chess player, a Grandmaster, and the 8th World Chess Champion. He was often called "Misha", which is a diminutive for Mikhail. He was also called "the magician from Riga"... At the age of eight, Tal learned to play chess while watching his father, a doctor. Shortly thereafter he joined the Riga Palace of Young Pioneers chess club. His play was not exceptional at first but he worked hard to improve..." (source Wikipedia)

Puzzle #14 comes from one of his games: Tal - Feuerstein, simul, Stuttgart 1958. What is this position about? Well, any position from Tal's games is first and foremost about spectacular and unexpected sacrifices; this one is no exception. It all comes down to observe what pieces are under attack and what possible exchange sequence gives White the edge. The g5-pawn can take on "f6" and "g7", followed by a deadly "g8=Q#". That is a huge line, so how do we force Black to fall for it?
