Chess Puzzle: Easy For Humans, Impossible For Computers #3

In this video I am testing Komodo 10.4 chess engine with a very complex chess puzzle composed by English chess composer Harold Lommer. As White needs to develop a long strategical idea in order to win, the engine fails to calculate up to the end, the evaluation goes wrong and can’t solve it! A very unique chess puzzle where underpromotion to a knight is the answer!
Harold Lommer, Szachy,1965
