Interesting position from Jouni Uski

Thanks Bob

Yes indeed that was the explanation. I have to say I dont like that feature though, leads to confusion like this.

Wouldn't it have been better to just print the the final PV at the end of the small depth searches, so what, it scrolls a few lines of text up the screen.

I don't use "analyze" enough to have noticed this. I will at least see if I can make do something better. Here's the problem issue however:

Someone once suggested that if it sees a mate, it displays that output regardless of the "noise" setting. But that introduces a different form of confusion. At (say) depth=3, the first move searched leads to a forced mate (a loss), so it would display that. But then it would find a better move, but now not yet having satisfied the "noise" requirement, it wouldn't display that. Leaving the "I am mated" analysis as the only thing visible...

It can be fixed, but it is a bit messy...

My suggestion is to ensure the PV has been printed when the search terminates.

That is easy to say, but it is more complex to actually do. I make the decision to print (or not print) the PV at time T. The iteration ends at time T+n.

If you decide not to print the PV at time T, you could copy the PV if necessary, and set a flag.
