Something seems to be wrong with Smooth Scaling and Stockfish 1.9
Admittedly this test is rather unscientific, e.g. there were two losses on time (Stockfish 1.9 JA 64bit - Shredder 12 UCI 1-0 and Critter 0.80 64bit - Stockfish 1.9 GTB 64bit 1-0) because my computer went into sleep mode. But still, others have reported bad results with the SS version also.
