Also I fear that my wording might have added to the confusion. Here is a constructed game of Engine X (no opening book) that will ponder like I think Ruffian does: 8 +0.22 e4 e6 2. d4 d5 3 3. Sc3 It plays 1. e4 and starts to ponder 8 -0.22 e6 2. d4 d5 3. Sc3 8 -0.11 c5 2. Nf3 Nc6 9 -0.00 c5 2. Nf3 d6 After some time the opponent answers 1...c5, and Engine X replies with 2. Nf3 (the second move in the PV according to my strange terminology). I also don't see how you could do this in UCI, but as Ruffian is obviously installed as an UCI engine with CP here .. - who knows. I thought about checking for real with logfiles now to make less of a fool of myself, but then I hope someone who both knows Ruffian 2 and more than me, might explain instead and save me the time :).
