Movei is already running for almost 3 hours on these positions. I do other things like posting at the same time but they do not cause big slow down. 11 1139 22151 47686072 b5e5 h6d6 g1b6 c7b8 e5d6 b8a8 a6b5 e7c8 b5c6 d7c6 d6d8 e 8d8 b6d8 c6d7 c1c5 g4f3 g2f3 11 1139 88188 189632493 b5e5 h6d6 g1b6 c7b8 e5d6 b8a8 a6b5 e7c8 b5c6 d7c6 d6d8 e8d8 b6d8 c6d7 c1c5 g4f3 g2f3 12 1169 89243 191639687 b5e5 12 1239 89281 191700782 b5e5 12 9983 90015 193452849 b5e5 h6d6 g1b6 c7b8 e5d6 b8a8 a6b7 a8b7 d6c7 b7a8 c1c4 d7c8 c4a4 c8a6 a4a6 c6a7 a6a7 Uri
