Body: <p>I am programming a basic chess AI, within it I have my evaluation function.
  It is simple, only uses piece square table values, and does basic calculations for the pawn structure and king safety.</p>
  <p>How would I go about testing the accuracy of my static evaluation function, is there a website which hosts a powerful one for me to compare to?</p>

  I am programming a basic chess AI, within it I have my evaluation function.
  It is simple, only uses piece square table values, and does basic calculations for the pawn structure and king safety.
  
  How would I go about testing the accuracy of my static evaluation function, is there a website which hosts a powerful one for me to compare to?
