Eliminating the defender is one of the simplest methods to attack. Good analysis helps a lot with spotting who the defenders are, but this is only the beginning. Good, solid calculation is still required to bring home the victory. [b]Your tasks of the day:
a) Analyse the position and decide if "eliminating the defender" or "attacking on opposite sides" applies here
b) White to move and win the fastest possible way
c) Bonus question: can you guess the opening played just by looking at the position?[/i]

Puzzle #184 solution:
Cruz - Seirawan, Moscow Olympiad 1994. One third of the solvers observed the essential detail: Black's King is and remains in the square of all those White passed pawns long enough to stop them and get a new Queen. Philip and Ziyao has the best answers this time around. Ziyao:
a) King activity: Black's King is more active and can stop both pawns. White's king only supports one of his passed pawns, which although important, will not help him win/ save the game.
Black's King more or less occupies the center and plays an active role there.
Plans:
White's plan should be to advance his pawns ASAP before Black can create a passer and win.
Black's plan is to eliminante White's threats and create a passer, then push and promote it.
