However, after about 8 minutes, it gets stuck on g4 and DOES switch to it after 18:40 (just under 80 million positions -- depth 4/9). 1.g4 Rh8 2.Qxf7+ Kxh6 3.f4 Rg8 4.g5+ Bxg5 5.Qxb7 Nb4 6.fxg5+ Qxg5 7.Rf2 Raf8 with a score of 0.94 for White. The previous eval for Nxf7 was 0.11. At 30:34, depth 4/10, 127 million positions, g4 is still the move, but the eval has lowered to 0.44 and the new line adds "8. e4 Nd3" at the end. It has now been thinking for over an hour, 225 million positions. Since I don't want to lose this post to a random crash or power outage, I'll let you know if the move changes. jm
