What is the meaning of this: C0/R0/K2/P9/X36 AutoTurbo-Search for Special-Mate [C1/R0/K0/P0/X0] in 15 ... (Hash=33MB) AutoTurbo-Search for Special-Mate [C0/R1/K0/P0/X0] in 15 ... (Hash=33MB) I do not understand what is the meaning of "C R K P X" and maybe this is the default option for mate problems(I used chest only to find the shortest mate) but it seems that chest knew before starting that it is mate in 15 moves so it does not need to search for longer mates.
