Some of the problems are labelled to have errors in construction (失题). Most of such errors result in having multiple solutions, although one or two result in the problem having no solutions at all.

The complete set of problems can be found [ext] here. The format of the problems is as follows:

  第[Problem number]题 『[Who plays first]』

  【审题】[Problem description]

黑先 means "Black to play", 白先 means "White to play". Hope this helps.
