Chapter 15: Puzzles
Take a corner puzzles
Diagram 15-1 shows an example of a take a corner puzzle. The expression “White in 2” indicates that it is White’s move, and you are asked to evolve a plan that will enable White to occupy one of the board’s four corners on his second move. To solve the puzzle properly, your plan must deal with every possible defense for Black so that no matter what move Black makes he cannot stop White from occupying a corner on White’s second move. White need not prevent Black from taking a corner, as long as White himself can take a corner. The expression “or win” (see puzzle 9) means that the side to play must take a corner or win the game in the number of moves allowed. In some puzzles, the corner to be captured is specified. For example in puzzle 20, the a8 corner must be captured in 3 moves. In Diagram 15-1, White’s first move should be to b2. This allows Black only three options: a2, a3, and b3. Whichever move Black chooses, it will turn over the new disc at b2 and thus allow White to occupy a corner (a1) on his second move. | |

White in 2 |
Take a corner puzzles were popular in the 1980’s, but have largely disappeared in recent years, which is a shame in my view. One problem with take a corner puzzles is that, since the goal is to capture a corner rather than win the game, the solution is often not the best move available. Indeed, the solution to the puzzle could very well be a game losing move. Despite this esthetic flaw, I believe that working on these puzzles will help you develop the ability to read ahead. Solving take a corner puzzles is also a lot of fun! The puzzles below appeared in Othello Quarterly between 1979 and 1986.
