Chest used 15961 seconds on p200 to find the mate in 10 and it should be translated to less than 1 hour on fast hardware. Unfortunately there are programs that have no chance to find it in an hour because they stop to search when they find a mate. The smartest program in finding mates based on my experience is chessmaster but I am not sure if it can find the mate in less than an hour because I believe that this is not the kind of the mate that it likes(it likes more mates when there are more pieces in the board). I did not test chessmaster so I may be wrong. I also do not have all the 5 piece tablebases and I expected that maybe they can help in finding the mate in 10 because programs do not have to search after the last capture that leads to 5 piece tablebase position. Note that some tablebases like KQRP vs K may be also productive in finding the mate faster(in the main line of chest it gets KQRP vs K position in a position when black does mate in 3). Uri
