New chess engine: Euwe 1.3.0
Euwe is a UCI chess engine written in modern C++. It is named after Max Euwe, a Dutch chess player, mathematician, former FIDE president, and the fifth World Chess Champion.

Since this is the first release of the engine it is still relatively simplistic and has only moderate playing strength. Based on my own testing against other open source engines on CCRL I expect that it's strength (under 2'/1" time control) is about 2200-2250 elo. I'm excited to continue tinkering with it to improve it.
v.1.3.0:
Version 1.3 adds Linux build support.
It also includes several minor improvements:
Some bugfixes to draw detection code. This fixes issues where Euwe blindly walks into a draw
from a winning position.
Detect drawish material configurations in the evaluation function.
Use the transposition table in quiescence search.
The selective depth calculation has been modified to match the Stockfish convention (depth of the
deepest PV line, including nodes in quiescence search).
Fixes to reported statistics:
Use rounding to nearest permille for reported hashfull (instead of rounding down).
Reset selective depth after each full search to a given depth, instead of keeping a running
maximum for each 'go' command.
Approximate strength gain (on ultrafast time control): 27.9 +/- 7.8 Elo.
