In principle I like long PVs, therefore (and of course because of its playing strength) Many Faces is my favorite Go program. Several of you may laugh at me/it, but with some training a human can get a lot of information from long PVs. Several years ago I was very active in computer-assisted chess where I took the candidate moves from two different chess programs, and it was up to me (the human) to select amongst them. (I called that system 3-Hirn: 2 computer brains + 1 human mind. "Hirn" is German and can mean both brain and mind. When the computers were at Elo around 2500, me with my Elo 1900 made the 3-Hirn as strong as about 2700.) In 3-Hirn, I did not only look at the candidate moves themselves but also at the corresponding PVs (and at the evaluations). By time I learned to recognize "ill PVs" and such ill PVs were often a useful indicator for me not to select this move. (Of course, the more early the illness occurs in the PV the more serious would the reservations against that move be.) Having in mind the 3-Hirn approach also for Go (it will come: when in a few years bots will have 3-4 dan strength, a good human of low dan strength will be able to bring a 3-Hirn to 5-6 dan), I am pretty sure that PV watching will also be an important tool there. On the other side: Too long PVs are not really helpful. So for me, ManyFaces with maximum PV lengths of 10, 12 or 14 would be more comfortable than the very long lines it shows in its current version. This is a wish only, of course. Keep up your very good work, David!
