White to mate in 113.

Chest 5.2 is very fast telling me that there is not checkmate in 126 moves or less with Special, Automatic and AutoTurbo search modes with input KingSquares=3, PieceLimit=9 and MaxMoves=15 (the parameters that Chest gives when starting a normal search) after only 228 searched nodes, trying with all search orders (KPX, KXP, etc.). I need more training with Chest.

Well, actually, you just need to find the first several moves to win.
