I feel like I currently lack the knowledge to developed a well scaled HCE evaluation. As a result, I am focusing on NNUE. I've found a few NN training libraries online and I'm attempting to train my own NNUE. In the future, I planning to release a new version incorporating my own NNUE and even perha...

Hi, I hope you're doing well, I'm just wondering if there's an update for the evaluation of my engine. I'm especially curious for the rating of v2.0, and wondering if this version could be listed? Understanding the ongoing evaluations for numerous engines, I appreciate your team's efforts and will p...

I didn't update v1.1 with the second bug fix. However, I don't think v1.1 had this issue since it used a handcraft evaluation instead of nnue, so it should be good. I speculate the nnue version had that bug because during the endgame the nnue gave knight promotions a extremely high score (and knight...

I've implemented a fix and updated the exe and source code for the release: https://github.com/feftywacky/Thrawn/releases/tag/v2.0 I should've made another release ...

Hi, Thank you for the feedback! And I appreciate your patience! I've looked into the code and found out it to be a bug with the uci_loop and how I was parsing inputs. I've tested Thrawn_v2.0 and Thrawn_v1.1 by also using CuteChess Tournament mode: 4 games, 15sec + 0.1sec time control I have implemen...

no it does not.

if you refer to the README in the github repo, at the bottom I referenced the specific nnue dataset I've found online: https://tests.stockfishchess.org/nns

Hi, I've coded an open source uci compliant chess engine and would like it to be tested against other engines to determine its rating: https://github.com/feftywacky/Thrawn engine name: Thrawn name: Feiyu Lin Thrawn v2.0 evaluation type: nnue estimated rating: 2500+? executable: https://github.com/fe...
