30000 @ 15+0.05 th 1 Now TM changes are done versus shorter book. But after change to shorter book, number of moves per game made by engine increased, and results of current tm tests may be influenced by this. So check if relevant parameter is still optimal.

sprt @ 15+0.05 th 1 go back to something more similar to the first patch. The last patch fail fast and I do not know why so I did something more simple that is similar to the first patch but that has easy move only in cases that the difference is at least a pawn.
