Body: <p>I hope this is the right forum for my question.</p>
  <p>So, I have all 5 men files on my HDD and the two files</p>
  <p>KRPPvKR.rtbz</p>
  <p>KRPPvKR.rtbw</p>
  <p>In the position here (8/2K2k2/3R3P/5P2/8/8/8/r7 w - - 0 10) everything looks good.</p>

  <p>But if I play the move 10.h7, Angie starts calculating. Stockfisch is right, 10... Kg7 is a draw, but something is wrong.</p>
  <p>Does anyone have an idea why the engine starts calculating here?</p>
