If white achieves this position it's a drawn as the bishop and knight are creating a barrier around the king (a3, b3, c3, c2, c1) but is there any simple pattern to achieve this position and defending it as white? It looks kinda hard
Very nice . I did not know this draw fortres. But to Always reach this is impossible. For example.
I set up the following position. and it is. White to move is a draw. ( 1.Nd4! = ) But back to move is a win for black.

Not totally relevant, but endgame manuals usually describe two knights v queen as generally drawn. Fine (and probably many others) also describes two bishops v queen as generally drawn.
I think that's because most popular endgame manuals are old and their authors not likely to revise them from their coffins or wheelchairs. Once they are replaced or corrected in due time, players will probably put more effort in attempting to win theoretically won endings and thereby get better scores. 50M permitting that is.
It is not true. Two Bishops mostly lose against a Queen just as a Bishop and a Knight. Only the two Knights mostly draw.

The two knights don't mostly draw either according to Nalimov - by a large margin. See the figures I posted in #18.
