Mate in eight

This puzzle came from a game in February's Untitled Tuesday tournament.  White missed the mate in eight, but did eventually win.

I got four out of eight right, but one of them was exchangeable, I believe.

I'm pretty sure I know a couple of the moves you didn't get right. grin.png

 

I think a lot of strong players would miss that mate even in slow time controls.

Awesome sequence - you're kinda forcing the position into a back-rank problem, even though his King is on f6 tongue.png what rating would you expect of someone who could see this and execute it over the board?

Shockingly, I got it right away - but only because I knew it was there.  In actual OTB play, I likely wouldn't have bothered to look that far ahead.  If I were playing the actual game, I would have certainly played the start of the sequence, but after 17. ..Ke6, I would have forked the black queen with 18. f5+!, and called it a day.  I mean, who is going to pass on a queen for two pawns?

Also, you don't have to sac the queen, 21. Bd7+! does the same thing.

I would guess that it would be rare for anyone below master level.  I wouldn't be surprised if GMs would sometimes miss this.

 I suggested that, but there's too many positions with multiple winning moves, and the tactics trainer currently only handles one winning line.

I got everything wrong on each and every try.
