Execution

 When you have 2 move (3 ply deep) problems, one move is used for the actual execution of the wood gaining process, while the other move either prepares the execution or deals with the consequences. In 54% of the cases the first move is a preparational move, while in 46% of the cases you start immediately with the execution.

The level of the problems is between 1800 and 1850. This is the division of the executing moves in frequency of occurrence:

• B.A.D. (Barely Adequate Defended) piece 46%
• Mate 22%
• Duplo attack 16%
• Promotion 11%
• Trap 5%

In general, the salient cues that give away the executional moves are not too difficult to spot with hindsight. This means that you have to find the preparational moves or the moves that deal with the consequences. These moves must be revealed by logic thinking. By answering the question "how can I make this executional move work?".

If you don't know what the executional move is, you cannot start with logical reasoning. So you must hoover above the board spiralling in vulture mode, until you know what you want to achieve. Then the logical process starts.

The large amount of B.A.D. (Barely Adequate Defended) pieces might seem strange. But when you look it up in the database, there is usual a good reason for that. For instance you are halfway an exchange, you are harvesting a trapped piece, you punish an incorrect offer, or you sacced a piece yourself which your opponent shouldn't have accepted. Or it is simply move 39 where even grandmasters in time trouble can go astray.
