It is both in analysis mode and in infinite-rebel to move. Rafael, a couple of comments, 1) The strange NPS numbers are caused by an overflow of the counters, it is just a harmless display glitch. 2) The worrying part comes from this: 00:00:07 10.00 1.39 1.c4 dxc4 2.Nxc4 f5 3.Qxe8 Rxe8 4.Rac1 00:00:44 11.00 1.49 1.c4 Qd8 2.cxd5 exd5 3.Rac1 Ng5 4.Kh1 00:06:49 12.00 1.32 1.c4 Qd8 2.cxd5 exd5 3.Rac1 Ng5 4.b4 00:32:01 13.00 1.30 1.c4 Qd8 2.Rf4 dxc4 3.Nxc4 Bd7 4.Nd6 The branch factor is 6-8 which is impossible in normal play. The only conditions such a thing to happen: a) Rebel 12 (DOS) has been set on the taskbar for some time either by ALT_TAB or by an active screensaver; b) Your processor is overheated; c) Somewhere on your system another program is running that eats a lot of processor time. I suggest you to re-run the position.
