"Well, there are plenty of bishop and knight mates, but the elementary mate is a bishop, knight, and king against a lone king. In that case, yes, the king will be as involved in the mate as the bishop and knight, and it is a very difficult mate to master. It probably isn't worth learning at your level, at least in my opinion, as it is extremely rare and fairly difficult."
I disagree. You should learn how to mate with Knight and Bishop as soon as possible. It doesn't turn up as often in games of higher rated players, because the other player resigns before being forced to mate with Knight and Bishop. But in the lower rated games it is more likely to appear as the opponents play on until the end quite often, regardless of material advantage.
When you are consistently making major tactical blunders, studying rare endgames is not the most efficient use of your time.
I, for one, have never encountered this endgame, and it is clearly quite rare. It may be the case that masters usually resign such endgames, but even if they didn't, they do not come up often. According to Müller & Lamprecht, the checkmate occurs in only one in 5,000 games (that's 0.2%). So rather than spending quite a while mastering the bishop and knight checkmate to improve his win rate by 0.2%, Mystic could probably better use his time learning basic tactics and maybe endgames and at least one or two good openings than complicated mates.
It's not that he should never learn the mate, he just shouldn't bother at this rating. At a higher rating, it will become more important (and easier).
You could have done better on some moves.
Yeah I know, I'm just thinking of what happened during that game for me to just, go...brain dead.
