How do you win with a queen vs a knight and bishop?
Queen vs Knight and Queen vs Bishop are both theoretical endgames the Queen side should win, but I don't think Q vs B + N is as clear cut. The Bishop and Knight side might even be able to setup some fortress-type position and hold out long enough for the 50 move draw rule. However, as the Queen side, I'm sure the goal would be to try and separate the pieces (where they can't coordinate with each other) and then win one (or both) by forks, pins, skewers etc.
Just be careful with the fact that if you lose your Queen to a fork, then the Knight and Bishop side might be able to force checkmate as B + N checkmate is a theoretical endgame (a tough one to learn, but theoretically a forced win).
However, the chance of getting exactly Q vs B + N is so miniscule and the method so situation-based that it probably isn't even worth studying honestly.
