Stockfish , chess engine UCI Rating JCER = 3389 🔬 Author: Joost VandeVondele Timestamp: 1513498315  Make staticEval independent of the search path  Current master can yield different staticEvals depending on the path  used to reach the position. The reason for this is that the evaluation after a  null move is always computed subtracting 2 * Eval::Tempo, while this is not  the case for lazy or specialized evals. This patch always adds tempo to evals,  which doesn't affect playing strength:  LTC  LLR: 2.96 (-2.94,2.94) [-3.00,1.00]  Total: 59911 W: 7616 L: 7545 D: 44750  STC  LLR: 2.95 (-2.94,2.94) [-3.00,1.00]  Total: 104947 W: 18897 L: 18919 D: 67131  Fixes issue #1335  Bench: 5208264  ⭐⭐⭐    Stockfish 17121709 - download

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.
