Do rated games with 3N 3 B or 3 R exist?


Of course the three pieces belong to one side :) and the extra piece had been obtained by underpromotion


I read somewhere that in the 19th century the chess master Mackenzie played a masterpiece where he underpromoted about 4 times. I don't know the opponent or the game. It might hold the underpromotion record if I recall from a Chernev book.


There are problems and studies where three Bishops or Knights appear on the board, and there are real games where a third piece was obtained by underpromotion, but I don't know of any games where there were three of the same minor on the board at the same time.  I don't believe I've ever seen even a puzzle with three Rooks in the solution.
