What's wrong with using smothered mate in 5? So it takes one move longer, so what? How is that incorrect? Someone explain that to me, I think it's absurd. 

Nice!!

You might've answered your own question, PAMetalBoss... one move longer could mean the difference in a blitz/bullet game, or even a regular slow play  match with time running out. The fewer the moves to checkmate, the safer and less chance for error, or even a mishandled piece.  The smother mate damages your opponent's ego and will more, yes, but not if he/she has 1 second left and you have none.  Then you'd just look like an idiot.

Came here to say this. Glad it had been mentioned. Also, I'd take another move for style points.

I was blindsided. I was so into the smothered mate pattern that I failed to consider any alternatives.

Ah well, good one.

Not as efficient, but prettier is smothered mate:

1. Qd6+ Ka8  

2.Nc7+ Kb8  3.Na6+ (double check) Ka8

4.Qb8+ RxQ

5. Nc7++
