Simplify Pv nodes related logic in LMR

Instead of having 2 separate conditions for Pv nodes reductions we can actually write them together. Despite it's not being strictly logically the same bench actually doesn't change up to depth 20, so them interacting is really rare and thus it's just a removal of extra PvNode check most of the time.

May be this is a temporary problem. Doesn't have any issues so far with box.

Regarding chess engines for Android, an own section for Android, where each engine has its own thread, would be nice. Make things easier to follow.

Good start also for Koivisto in the FCP Tourney 2022, which seems on par with Fire. Needs a lot of more games, of course.

https://www.amateurschach.de/fling/fcp-tourney-2022.html

On Android, Koivisto is not the fastest one, because there is no native NEON support (only available through the sse2neon header).

Koivisto 7 (armv7) and 7.5 (armv7) work well in Droidfish, but always lose on time after move no. 1 in Chess for Android v6.2.1.

I'm sure, the download problems wit box have to do with bandwidth usage. Too many downloads within a month. There is one thing, i can do, deactivating the public link to my repository (not really necessary). In the meantime, i will post additional links.

The GCC compiler is not always the winner. Fastest results for Koivisto are made with Clang and Android NDK. With Clang and PGO you may achieve 1 or 2 % more nps. It's not worth the effort.

I can confirm, Koivisto is not working on Chess for Android (for whatever reason).

- Support for 32 -> 64 pieces
- Null move pruning back to where it was. In v6.1 it was bad in EG
- Small fixes / +5 Elo
