Programs even cannot see at tournament time control that the following position is a draw: [D]8/8/5p2/5kRp/5p2/1p6/p2r4/K7 b - - 0 4 No program tries to generate a table like the following way: 1) black king e6 white rook e5 reason diagram 2) black king e4 white rook e5 reason diagram 3) black king d6 white rook e6 reason 1,4 4) black king d7 white rook e7 reason 1,3 5) black king f7 white rook e7 reason 1 6) black king f3 white rook e3 reason 2 7) black king d3 white rook e3 or d5 reason 2 8) black king d4 white rook e4 or d5 reason 2 9) black king c5 white rook c6 reason 3 10) black king c7 white rook c6 reason 3 11)black king d5 white rook d6 or e5 reason 3 12)black king d8 white rook e8 reason 4 13)black king c8 white rook c7 reason 4 14)black king c6 white rook c7 reason 4 I believe that it is possible to prove by this kind of table that the position is a draw but unfortunately I know no chess program that can generate this kind of table.
