I can think of 2 or 3 that come to mind (there are more but this is just my opinion)
Harry Pillsburys win over Siegbert Tarrasch in game 10 August 1895 at Hastings
Bologolyubov-Alekhine Hastings 1922
Emmanuel Lasker vs William Napier Cambridge Springs 1904
A game so complex that it's kept Masters baffled for decades
The most impressive?
