I agree that those positions are rather useless for testing. But nevertheless WAC represents the positions of the book "Win At Chess" by Reinfeld, if they are good or bad. For testing one could also remove such positions which are solved by all programs in nearly 0 seconds. But on the other hand they might help to detect if something is broken. >I am not going to be surprised if WAC 150 >is going to have even 10 different correct solutions > >Kh7 is another solution to WAC150 that was not mentioned >and there are probably more solutions and >I do not think to check it.
