I also cannot see and the original position may be a draw with exact game If someone decide to build the 6 piece tablebases for 4 pieces with blocked pawns(white pawn at h2 and black pawn at h3) we may know. Maybe it is a good idea to tell chess programs to build these tablebases during a game when the hardware is fast enough and it is tournament time control. It may be a very good option for correspondence games even today. Even if programs need 30 to build these tablebases it may be possible to do it at some tournament time control games when this kind of position is in the root and the program may use 30 minutes for one move but later play always from the tablebases.
