Minimal thinking time, even if only one rootMove.
...
without search, the eval returned can be misleading (e.g. mate instead of draw),
leading to wrong adjudication. With a minimal search, this is avoided.
This patch leads to 1ms long searches if there is only 1 move,
similar patches all indicate a small Elo gain.

Give bonus for bishops that are alligned with enemy kingring.

Inspired by the succesful patch "Give bonus for rooks that are alligned with enemy kingring" from Vizvezdenec,
this idea has been reused for bishops. Here, we only consider attacks that are not blocked by any pawn.
Also we have a 50% higher bonus than for the rooks.

* attacks_bb<PieceType>(square, bitboard) gets attacks considering occupied squares in the bitboard).
* pawn_attacks_bb(Color, Square) gets pawn attacks like other pawn attack bitboards.
* Wraps all access to PawnAttacks arrays and PseudoAttacks arrays and adds asserts as appropriate.

Give bonus for rooks that are alligned with enemy kingring
...
The idea of this patch is that if rooks are not directly attacking the opponent king,
they can support king attacks staying behind pawns or minor pieces and be really
deadly if position slightly opens up at enemy king ring ranks. Loosely based on
some stockfish games where it underestimated attacks on it king when enemy has one
or two rooks supporting pawn pushes towards it king.

This patch is a combinaison of two recent parameters tweaks which had
failed narrowly (yellow) at long time control:
• improvement in move ordering during search by softening the distinction
between bad captures and good captures during move generation, leading
to improved awareness of Stockfish of potential piece sacrifices (idea
by Rahul Dsilva)
• increase in the weight of pawns in the "initiative" part of the evaluation
function. With this change Stockfish should have more incentive to exchange
pawns when losing, and to keep pawns when winning.

Avoid sending info strings before 'uci' has been received
...
Do not send the following info string on the first call to
aligned_ttmem_alloc() on Windows:
info string Hash table allocation: Windows large pages [not] used.
The first call occurs before the 'uci' command has been received. This
confuses some GUIs, which expect the first engine-sent command to be
'id' as the response to the 'uci' command. (see https://github.com/official-stockfish/Stockfish/issues/2681 )

Increase base time use and limit max used.
...
This change increases the base part of optimumTime at all depths. It also reduces the size of max_scale and thus maximumTime by using a linear scale instead of pow(x, 0.3) and by limiting max_scale to no more than 7 (previously as high as 8 or 9 at very high depths).

Don't adjust MoveOverhead by increment

This is a change to address a potential timing issue for slow networks.
Move Overhead was limited by TC increment,
which might be problematic if small increments (or sudden death)
on slow networks (needing high Move Overhead) are used.

Simplify Time Management
...
This is a functional simplification of the time management system.
With this patch, there is a simple equation for each of two distinct
time controls: basetime + increment, and x moves in y seconds (+increment).
These equations are easy to plot and understand making future modifications
or adding additional time controls much easier.
SlowMover is reset to 100 so that is has no effect unless a user changes it.
There are two scaling variables:
* Opt_scale is a scale factor (or percentage) of time to use for this current move.
* Max_scale is a scale factor to apply to the resulting optimumTime.
There seems to be some elo gain in most scenarios.
Better performance is attributable to one of two things:
* minThinkingTime was not allowing reasonable time calculations for very short games like 10+0 or 10+0.01. This is because adding almost no increment and substracting move overhead for 50 moves quickly results in almost 0 time very early in the game. Master depended on minThinkingTime to handle these short games instead of good time management. This patch addresses this issue by lowering minThinkingTime to 0 and adjusting moverOverhead if there are very low increments.
* Notice that the time distribution curves tail downward for the first 10 moves or so. This causes less time to attribute for very early moves leaving more time available for middle moves where more important decisions happen.
Here is a summary of tests for this version at different time controls:
