Game 6
The last move is a real shocker.
[pgn] [Event "?"] [Site "Duesseldorf"] [Date "1908"] [Round "?"]
[White "Alekhine"] [Black "Koehnlein"] [Result "1-0"] 1.d4 d5 2.Nf3 e6 3.e3 Nf6 4.Bd3 Nbd7 5.Nbd2 Bd6 6.e4 dxe4 7.Nxe4 Nxe4 8.Bxe4 O-O 9.Bg5 Qe8 10.O-O f5 11.Bd3 e5 12.dxe5 Nxe5 13.Re1 Qh5
14.Nxe5 Qxg5 15.Bc4+ Kh8 16.Qxd6
1-0
Game 9
The following is from a simul (playing multiple players at the same time).
Black will be mated on h8 soon. If Qxg6 18.Qc4+ and eventually black will put a piece on f7, blocking the king's escape square.
If Alekhine hadn't played Ne5 and caused the black d pawn to move, black would have d5 after 18. Qc4+. 🙂
Game10
Here is a miniature win over Aaron Nimzovich (author of My System and father of the hypermodern movement). For some reason, Nimzovich grabs every pawn he can.
In the end, Nimzovich is all tied up from all the pins. White's threat is 1.Nxe4 fxe4 2.Qxh7+ and 3.Rf1+ If 19. ...Kg7 20.Nxe4 dxe4 21.Bh6+ Kf6 22.Rf8+ wins the queen.
