Isa 1.9.8 - winboard chess engine

Image
Isa - winboard chess engine About engine: Isa is a chess engine I developp during my free time. Chess programming is my hobby since the 80's years. I started developing with QuickBasic 4.5 (I wrote a weak engine named Bishop) . Then I learned the C langage and studed the TSCP source code (like everyone I think) . « Titan » and « DCP » (DCP = Titan + winboard protocol) was born . Strengh was always so weak , around 1400 elo . After that I rewrote again my engine and Jars came out (I released Jars) and then Yoda (both played around 1800-1900 elo. After finding dificult to improve , I stopped working on both engines and started to work on Isa , a diferent way. I started Isa from Firstchess.c source.

Stockfish  - chess engines UCI Previous version chess engine Stockfish   Author compilation -   syzygy       Information on the compilation: Timestamp: 1477542382  Output PV if last iteration does not complete  Instead of outputting "info nodes ... time ..." when the last  iteration is interrupted, simply call UCI::pv() to output the PV.  I thought about calling UCI:pv() with bounds -VALUE_INFINITE, VALUE_INFINITE  to avoid "lowerbound" or "upperbound" appearing in it, but I'm not sure that  would be any better.  This patch fixes rare inconsistencies between the first move of  the last PV output and the bestmove played. It also makes sure  that all the latest statistics are sent to the GUI (not only nodes  and time but also nps, tbhits, hashfull).  No functional change.  Stockfish 16102706  - download
