Eval Sample 

    

      Press Test Eval (top row). We'll try eval and capture NNUE/classic strings; if unsupported, we'll run a short search to show UCI info score lines.
    

    

  


  

    Tip: leave the box blank to try filenames in the current folder. Or type a directory like engines or /sf to probe inside it.
    If you see a threads error, use a single-thread build or serve a pthread build with COOP/COEP and keep Compat OFF.
