This exact same puzzle was discussed extensively on this Forum (or the More Puzzles forum) in the last 3 months. You may care to scroll through the list.
Tablebases are always right. If chess.com contradicts it, it is certainly wrong. The chess.com lessons and onboard engines are not perfect while the tablebases are.
I recall this is a hard endgame so it is easy to go wrong.
I'm trying to work through the Intermediate Draws in the Pawn Endgames section and I can't figure this one out for the life of me. I keep going wrong. To make matters worse, the chess.com "assistance" gets it wrong too, either failing to evaluate the position as a draw, telling me that the only right move (according to the table base) is a losing mistake, or giving me hints that are losing. I'm struggling to understand what principles of pawn endgames (e.g., opposition, key squares, corresponding squares, etc.) apply here and will help me toward the correct solution. Can anyone help?
Am I missing a key concept that makes the solution obvious, or is this just an example of chess.com mislabeling the difficulty? Thanks.
