Haha! Whoa, yes, it does! And it works for any engine! This is a clever solution, and I was having to edit engine code and make my own compile to achieve what adding this line on option doesGabor Szots wrote: ↑Thu May 09, 2019 7:58 amThank you for your reply. I edited my Komodo eng file to include a line MultiPV=6, only I don't know whether it has an effect.Ovyron wrote: ↑Wed May 08, 2019 8:48 pmIt seems that you can't set MutiPV under the Shredder GUI (it hides the setting in engine options, and doesn't allow to set it directly; I had to make my own compile of McCain that calls it "MultiPW" just to fix this.)
The best you can do is using the F6 Key to increase MutiPV lines by one, and the F5 Key to decrease them by one, but it's impossible to play MultiPV games in the Shredder GUI (as it defaults to 1 in play mode.)
So here's the thing, Shredder GUI doesn't know this is Multi-PV output, so it treats it like normal output. If you're using an older version of Shredder Classic, right-click the analysis panel and tick the "Continuous Display" option so you don't mix anything.
The difference is that on normal output the best move is always shown at the very bottom of the analysis, while with a setting like MultiPV=6, the 6th best move is shown at the very bottom, with the 5th best in the previous line, and the 4th best in the previous line and so on.
I believe this was the reason engines like McCain's Tactical Setting or ShashChess's Deep Analysis Mode just switch MultiPV like this (no different than setting MultiPV in engine options), except they hide the scores of non-best moves so the score of the best one still appears at the bottom (even though for analysis knowing the scores of all those moves for free is very useful, not just finding the best move unattended.)
Thanks for this concept, now all engines that support MultiPV are able to use McCain's Tactical Setting by setting it in engine options
