These are often referred to as "mate in n" – for example "mate in three" (a three-mover); two and three move problems are the most common.
Each block started with a 2-move problem while the following 3, 4 and 5 move problems were presented in random order.
Therefore, we differentiated between easy (average of 2 and 3 move problems) and difficult problems (average of 4 and 5 move problems).
Note: Results on performance in healthy subjects suggested that 2 and 3 move problems were mostly solved in the minimum number of moves [ 11], which was not true for 4 and 5 move problems.
All subjects received ample instruction about the applied tests and were familiarized with the tasks by solving, in the case of the SOC, several one and two move problems, and in the case of the WCST, one run.
The truck — an old farm vehicle now sitting on a cobblestone street in America's largest city — had been the answer to my moving problem.
But some concerns were raised that it would just mean moving problem social-housing tenants to different areas.
As a government there's a lot for us to do there, but it's a fast moving problem that we as an industry need to tackle".
Solving a fast moving problem like climate change requires a fast moving governance system.
(Otto Blathy had composed a "mate in 292 moves" problem in 1889, albeit from an illegal starting position. ) However, in May 2006, Bourzutschky and Konoval discovered a KQNKRBN position with an astonishing DTC of 517 moves.
One block consisted of a 2, 3, 4, and 5-move problem with two different trials per problem, respectively.
