What's new:

Introduce lazy evaluation

After we have taken into account all cheap evaluation
terms, we check whether the score exceeds a given threshold.
If this is the case, we return a scaled down evaluation.

Keep pawns on both flanks

Positions with pawns on only one flank tend to be more drawish. We add
a term to the initiative bonus to help the attacking player keep pawns
on both flanks.

Stockfish 2017.02.11.ACH for Android


Alexei Chernakoff's successful attempt to prepare engine builds for Android is good news for mobile chess fans, bearing in mind Jim Ablett's fruitful return which quickly turned to a long break and Aprijal Pasaribu's determined but time-limited passion for compiling.

Alexei's first choice of engine is not surprising at all. He began with a current development version of Stockfish.

Implement an old Russian proverb

"Loose pieces drop, in blitz keep everything protected"

Adding a small S(2,2) bonus for knights, bishops, rooks, and
queens that are "connected" to each other (in the sense that
they are under attack by our own pieces) apparently is a good
thing. It probably helps the pieces work together a bit better.

Android Cfish-210418 (arm7 and two versions arm64v8.The Cfish-180418CL is built with the new Clang-5.0 and a little faster. But may not work on all devices. Use the normal version then).
