Sparring Milhouse versus Chinook

Well, I’ve mucked around a bit, and begun to add PDN (Portable Draughts Notation) logging to Milhouse. Here is a sparring match between the novice version of Chinook that you can play online versus Milhouse, running at around 15 ply search with a six piece endgame database. It seemed clear that the position was a draw at the end. Chinook seemed to think I had it on the ropes around move 19. Did milhouse miss a strong line, or is the novice level of Chinook misguided? I’m not sure.
