How to checkmate a lone king with 1 bishop and 2 knights?
Checkmate with 2 bishops is easy and logical.
Checkmate with 2 knights is known impossibly to force.
Checkmate with bishop and knight is known possible - and notoriously hard to perform correctly.
Checkmate with 3 knights is known to be possible to force - but since it requires underpromotion, understandably rare.
With 2 bishops and 1 knight, since 2 bishop checkmate is easy and logical, the bishops can simply perform the 2 bishop checkmate and ignore/disuse the surplus knight.
But 1 bishop 2 knights? Since disusing a knight means the notoriously hard KBN checkmate, how can 2 knights best be coordinated for an easier and safer checkmate?
