The famous Alekhine 5 Queens game Alekhine vs NN, 1915  (C12) French, McCutcheon, 29 moves, 1-0 Not proved dubious, but I don't believe it was really played.. R Steel vs R Macdonald Ross, 1884  (C25) Vienna, 25 moves, 1/2-1/2 A tad harsh.....Tim Krabbe thinks it is genuine. Tylkowski vs A Wojciechowski, 1931  (A03) Bird's Opening, 40 moves, 0-1 This one is likely to be true.... M Ortueta Esteban vs J Sanz Aguado, 1933  (C00) French Defense, 35 moves, 0-1 Declared a hoax by Tim Krabbe in Chess Curiosities C van de Loo vs M Hesseling, 1983  (C57) Two Knights, 48 moves, 1-0 16....Na6!! leads to stunning complications that favour Black C van de Loo vs M Hesseling, 2008  (B12) Caro-Kann Defense, 54 moves, 0-1 6 games
