He should have the KQPKP tablebase to make this endgame work properly. It may even be counter productive to have any "Pawn" tablebases without the proper "Promotion" tablebases to follow up. For the KPPKP tablebase you should have the KQPKP and KPPKQ at the very minimum. These endings are usually easy wins for the side with the Queen but that does not mean that they are not required for the programs to transition into them correctly from the KPPKP ending. Jim Walker
