Personally, I feel like SF has been tuned to death recently and that we
need to step away from existing-parameter tunes for a bit and focus more
on new ideas. I don't really think there's much more ELO in these tunes
(for now). For me at least, this was the last existing-parameter tune I'll
be running for quite a while. Cheers!

How to continue from there?

The values in the rook table now look a bit strange for a human eye
and are hard to explain, maybe it would be nice to simplify them
by hand and see if we can pass another (clean) double green with a
more regular array.

Change default contempt from 21 to 24 centipawns

To top the rating lists and get more interesting middle play, it
is a good habit to set the default contempt to the highest value
that does not regress against contempt=0. We recently decreased
PawnValueEg it is logical that to raise a little bit the default
higher contempt because of the following internal dependency in
line 334 of search.cpp :

````
int ct = int(Options["Contempt"]) * PawnValueEg / 100; // From centipawns
````

STC: contempt=24 passed non-regression vs contempt=0
http://tests.stockfishchess.org/tests/view/5bd6d7f80ebc595e0ae21e14

LTC: contempt=24 passed non-regression LTC vs contempt=0
http://tests.stockfishchess.org/tests/view/5bd6e0980ebc595e0ae21f07

On 2018-11-01, we also tested the effects of contempt=21 and contempt=24
against Stockfish 9, and the net result was neutral:

Contempt 21
ELO: 51.68 +-1.9 (95%) LOS: 100.0%
Total: 40000 W: 9487 L: 3581 D: 26932 Elo +51.68
http://tests.stockfishchess.org/tests/view/5bdb1a140ebc595e0ae2620a

Contempt 24
ELO: 52.21 +-2.0 (95%) LOS: 100.0%
Total: 40000 W: 9759 L: 3793 D: 26448 Elo +52.21

Clear TableBase mappings in Search::clear()

This patch will make possible to free mapped TB files with "ucinewgame" command.

We wrote this patch specifically to address a problem that arose while
running Stockfish with 7-piece tablebases as a kibitzer at TCEC for
extended periods of time across multiple games. It was noted that after
some time, the NPS of the kibitzing Stockfish (which is usually 3x faster
than the Stockfish actually competing) would drop precipitously, eventually
falling to preposterously low numbers until restarted.

Their eval bot basically inputs FEN, go infinite, stop and loop, it probably
didn't do ucinewgame either. As time goes it gradually slowed down and OS
starts to use swap, this is not reasonable since the engine only uses 16GB
hash and the machine has 1TB physical RAM and does nothing else.

How to continue from there?

The values in the rook table now look a bit strange for a human eye
and are hard to explain, maybe it would be nice to simplify them
by hand and see if we can pass another (clean) double green with a
more regular array.

Change default contempt from 21 to 24 centipawns

To top the rating lists and get more interesting middle play, it
is a good habit to set the default contempt to the highest value
that does not regress against contempt=0. We recently decreased
PawnValueEg it is logical that to raise a little bit the default
higher contempt because of the following internal dependency in
line 334 of search.cpp :

````
int ct = int(Options["Contempt"]) * PawnValueEg / 100; // From centipawns
````

STC: contempt=24 passed non-regression vs contempt=0
http://tests.stockfishchess.org/tests/view/5bd6d7f80ebc595e0ae21e14

LTC: contempt=24 passed non-regression LTC vs contempt=0
http://tests.stockfishchess.org/tests/view/5bd6e0980ebc595e0ae21f07

On 2018-11-01, we also tested the effects of contempt=21 and contempt=24
against Stockfish 9, and the net result was neutral:

Contempt 21
ELO: 51.68 +-1.9 (95%) LOS: 100.0%
Total: 40000 W: 9487 L: 3581 D: 26932 Elo +51.68

Contempt 24
ELO: 52.21 +-2.0 (95%) LOS: 100.0%
Total: 40000 W: 9759 L: 3793 D: 26448 Elo +52.21

Clear TableBase mappings in Search::clear()

This patch will make possible to free mapped TB files with "ucinewgame" command.

We wrote this patch specifically to address a problem that arose while
running Stockfish with 7-piece tablebases as a kibitzer at TCEC for
extended periods of time across multiple games. It was noted that after
some time, the NPS of the kibitzing Stockfish (which is usually 3x faster
than the Stockfish actually competing) would drop precipitously, eventually
falling to preposterously low numbers until restarted.

Their eval bot basically inputs FEN, go infinite, stop and loop, it probably
didn't do ucinewgame either. As time goes it gradually slowed down and OS
starts to use swap, this is not reasonable since the engine only uses 16GB
hash and the machine has 1TB physical RAM and does nothing else.
