Could someone give me some information about speed of the softwares for solving chess problems, specially helpmates? I have been testing a helpmate in 6 moves since morning, and until now Popeye didn't come to a conclusion. My position is heavy, there are just 2 white pieces (a king besieged in the corner and a pawn), but almost the entire black army is in service. One can assume that for each complete move (white + black) there are about 50 x 3 possibilities. That means, for the six moves of my problem a software using the "brute force" algorithm must evaluate around 15 trillion positions. Is that much for the present softwares and personal computers? I don't know. Thanks for any comment.

If you use "Option Intelligent" then solving should be fairly quick.
