William submitted a Comment to Problem 2254. Possible Opponents Matrix for single-elimination tournament

Faulty test suite. The 'for v = 1:10' in problem 5 has a semicolon after it.

Asif, Thanks for the clarifications. In problem 2, I was aware of the rook at h3, but there is also a pawn at h5 that makes Kh7 a legitimate solution I think (one that is harder to detect programmatically). As in problem 9, it complicates the solution a little more than you intended.

Asif, I think that several of the problem solutions need review. 1. In problem 2, 'Kf7' should not be in the solution since it is adjacent to 'Ke7'. Isn't the correct result {'Kh7',''Kg7','Kf5'}? 2. In problem 7, the king could take any of the knights. Is the solution listed as pos = [] because there are 3 knights on the board? If so, why is the solution to problem 9 listed as 'checkmate'? If not, a solution to problem 9 would be {'Ka3','Ka2'}. Similar questions apply to problem 8. 3. Why is 'Kc7' not in the solution of problem 3? I'm afraid I have a lot to learn about chess!

Asif, Thanks, but my point is that the pawn is in row-1 in *both* cases, so they should both be in check or neither should be in check. Since you described 'x' as being the 'opponent King', I think that both should be in check.

Asif, I really like this problem, but I don't understand why 'h6' has 'Kg7' in check in Problem 2, but 'e1' does not have 'Kf2' in check in Problem 6. Aren't these two situations the same?
