December 24, 2018 marks the 150th anniversary of World Champion Emanuel Lasker's birth.
Lasker won the World Championship by defeating Wilhelm Steinitz in an 1894 match held in New York City, Philadelphia, and -- for games 12-19 -- Montreal.
Here is the final game of that match, along with fragments from other games from the match, and comments from both Lasker and Steinitz.

{Before the match, Steinitz said, "I believe that Lasker is a really fine
player. Moreover, the latter had the chance to study all my games, my books
and therefore my style and if I do lose he will have to beat me with my own
weapons…” (NYT, March 11, 1894). One of Steinitz's weapons was the Bishop
pair, and Lasker showed he had learned well...} 1. d4 d5 2. c4 e6 3. Nc3 Nf6 4.

23. Na4 $5 {[#] For me, this is the most interesting move of the middlegame:
it semi-threatens both Rc7 and Nc5, neither of which is winning, and both of
which can be stopped by Black's next move, which White of course saw. So why
play Na4? Partly, it may just be "maneuvering"... keeping the game going and
forcing the opponent to discern the threats from the non-threats and respond
accordingly. Partly, it is a way to encourage Black's pawns to move -- this
reduces their future mobility and weakens some squares (the pawns can't go
back) and so makes other maneuvers possible while limiting Black's defensive
options.} b6 24. Nc3 Bd6 25. Rd1 {Tying Black further.} Ne8 (25... Ke7 $2 26.

This win ended the match +10 = 4 -5, making Lasker the new World Champion.
"When Steinitz entered this contest he felt sure of victory. But when fate
went against him and he found himself, for the first time in his life, beaten,
he behaved with the utmost chivalry. His way of resigning the last game of the
match was to call for cheers for the new champion of the world.” - Lasker,
Lasker's Chess Magazine, 1906.} 1-0..
