Sam Loyd is a famous chess problem composer; see: http://en.wikipedia.org/wiki/Sam_Loyd.  He also competed in the famous 1867 tournament in Paris; see: http://en.wikipedia.org/wiki/Paris_1867_chess_tournament

I stumbled upon the following beautiful game (at the bottom, for the impatient ;) from that tournament when checking my database for games featuring the following opening:
http://www.chess.com/opening/eco/C45_Scotch_Game_Classical_Variation 

Particularly where the follow-up is 5. Be3 Bb6 -- I became interested because the line is featured in game #18 in Rudolf Spielmann's classic book "The Art of Sacrifice in Chess" (here is a review of a different book about him, not by him: http://www.chessville.com/reviews/RudolfSpielmannMasterofInvention.htm).  

Interestingly, after describing 5...Bb6 as "simple and sound, and avoiding many book variations", Spielmann goes on to sacrifice a piece in the middlegame to prevent his opponent from castling.

But back to Sam Loyd.  Checking my database, a game of his is listed as the first win by Black relying on 5...Bb6, and what a win it is!  In fact, the finish is so brilliant many have commented they don't believe the game actually occurred and rather that it was a composition; see http://www.chessgames.com/perl/chessgame?gid=1255320

Whether real or composed it is worth playing the solution as it combines a number of tactical motifs that should be at every serious chess player's disposal.  I won't spoil things by revealing all the tactical motifs, but it does rely on the so-called "Anastasia's Mate"

Without further ado then, can you find the mate in eight for Black?
