Who can verify so many moves? :)

Emne: Re: Queen + Pawn vs. Queen mates in 268

I setup a similar position in chess:
White: King a8, Queen h2, Pawn d2
Black: King f1, Queen g7

White wins in 76 moves by playing Qf4 or Qh3! All other moves lead to the draw or loose. I get this result from Nalimov Tablebase Server
on http://www.lokasoft.nl/uk/tbweb.htm

The larger board in Gothic Chess allows the black to survive more then 3 times longer (assuming Ed's software to compute Gothic Chess tablebases doesn't have bugs).

There is an easy solution to this. Ask Fencer to set up a position, suspend the 50 move rule, and play against this database. I will move for it. You can move for yourself. We play until checkmate.
