     Hi Uri
     movei has also no idea of this endgame. The variation
     given by the engine is a complete loss for White
     14 -175 52507 125405519 g5g6 f2e2 g6g5 e2c2 g4g3
     this is a terrible and losing mistake
     c2c8 g5h6 c8h8 h6g7 h8h2 g3g4 e5f5 g4g6 f5f4 g7f6
     and Black has an easily won rook ending.
     Kurt
