Any serious chess game (a game where you learn a lot) is a continuous battle back and forth like the Ocean waves. Both sides try to outsmart the opposition, searching and discovering hidden resources in each position they face.
Solutions do not have to be fancy! The truth is for any spectacular game, you play hundreds of so called "boring" games. It is up to you to see beyond the apparent boredom and keep your attention sharp at all times like in this example. Your tasks:
a) Analyse the position from this classic game
b) Starting with White to move play the best line you can put together

Total available points for this puzzle is 20. The answers will be published next week together with puzzle #196.

Puzzle #194 solution:
Sutiman - Georgescu, Bucharest 1957. A very messy position and a scary attacking idea against the White King made the majority of you to run away with a draw; example Ziyao (see solution).
In reality you must have tried to see if that attacking idea for Black was so devastating. Do not believe any words (written or spoken) until you have convinced yourself the moves confirm it or not. The three solvers who did it also found the correct solution. James wrote:
a) (After the moves are played: 1.Qxa8 Nxd3+ 2.Kb1 Nxb2)
Material: White has a Rook for a Bishop and two pawns.
King Safety: Black has a battery attacking b2 and a1. White has a Knight preventing Black form going to h7, and a Queen on the back rank, but Black has a Rook defending it. Black King is safer.
Center: Black controls three squares and White controls one.
White: Stop Black from threatening Nc4.
Black: Mate White before White stops the threat.
