This position was part of a very disputed World Championship match of the past. Black saw his Bf7 being attacked by the Rook battery, but decided he still had enough time to take a pawn on d3, attack white's Queen and pin the dominant e5-Bishop; not a bad result for a pawn exchange move, right? Your tasks:
a) Analyse the position and decide who's better
b) You are white and must find the best response line you can think of
Total available points for this puzzle is 20. The answers will be published next time together with puzzle #277.
Puzzle #275 solution:
Game Pollock – NN, Buffalo 1893. No less than 7 solvers saw the correct solution and this is a very good thing! Unfortunately identifying the tactics used by white proved to be a more complicated task, nobody listing more than 3 correct ones in their answers.
b) Tactics used for the solution:
Queen sac
Discovered double check (double attack)
Fork
Remove the defender
Rook sac
Back rank mate
