Disgracefully, I needed my computer to go farther. Programs that use hash will do much better, like Heiner mate solver. Time of search by brute force (perfect search). Celeron 600Mhz. LLchess mate solver. 4 moves - 0.44 sec 5 moves - 9.39 sec 6 moves - 2 min 45 sec Will try later, if it will be possible, to put my computer for search for night already for 9 moves. Maybe mate will come sooner that it is suggested after my branching factor. My selective search (one that find mate rapidly) here is useless. Thanks for your positions!
