First move is really hard to find, everything else is easy :)

im surprised that i got most of it, up until the end

 yes, the same for me.it took me a minute to find the first move and then all the others just flowed after i found it. 

From some old game, I can't remember which (it was in The Golden Treasury of Chess, I think).

 yeah, i'm not sure where it's from.i got it from chessmaster and i thought it was pretty good and decided to share it.

what an incredible puzzel!

imagine having the balls to pull that off in a game!

imagine being able to see that in advance?!

definitely teaches you the value of pulling your opponent in

cool!

 yes,it was pretty cool.

 yes it was in chessmaster.it was in the acadamy section under the rating exam.

wow... very insightful.....

What happens if 6 Bxb5 not Nxb5?

This does just "flow": It's too easy after the second check, because it's been worked from final position back, rather than being real. What the hell is the white king doing on f5, anyway?!

 Bxb5 leads to mate 1 move sooner 6 Bxb5 axb5+ 7 Kxb5 Ra5+ 8 Kxc6 Bd5# because Whites knight blocks d6.

The thing that has tired me with chess puzzles is how 99% sac the queen.

Whenever I see a puzzle I just look for how I can sac the queen, they are pretty easy after that.

For me a good reminder to keep the pressure on.

nice

I had a lot of trouble on move 7.

ADK

great puzzle. I got it. thanks
