### A mate suite to test multi-pv and new engines

Analyzed the positions by the mate solver chest
They include all the positions of all the pieces against the following pieces in their initial position

1)king(1 position)
2)king and a pawn(8 positions)
3)king and 2 pawns(28 positions)
4)king and 3 pawns(56 positions)
5)king and a knight or bishop(4 positions)
6)king and 4 pawns that include a7,b7 when the solution is mate in not more than 8 moves

Ordered the positions based on number of nodes to see the mate.

I think that it may be good if new engines can beat chest (meaning finding all the solutions in multi-pv with smaller number of nodes)
Note that i used for chest 1024 mbytes hash and I think chest that use only one core is deterministic in the number of nodes to solve a problem

Analyzed the positions by the mate solver chest
They include all the positions of all the pieces against the following pieces in their initial position

1)king(1 position)
2)king and a pawn(8 positions)
3)king and 2 pawns(28 positions)
4)king and 3 pawns(56 positions)
5)king and a knight or bishop(4 positions)
6)king and 4 pawns that include a7,b7 when the solution is mate in not more than 8 moves

Ordered the positions based on number of nodes to see the mate.

I think that it may be good if new engines can beat chest (meaning finding all the solutions in multi-pv with smaller number of nodes)
Note that i used for chest 1024 mbytes hash and I think chest that use only one core is deterministic in the number of nodes to solve a problem
