Quarter-Finals
Match Two: Botvinnik v Alekhine
Game One
Mikhail Botvinnik - Alexander Alekhine
Nimzo-Indian
1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.e3
Botvinnik helped popularise 4.e3 over previous-favourite 4.Qc2.
4...0-0 5.Bd3

Alekhine never faced 5.Bd3

Stockfish11 and Komodo11.01 have a sharp difference of opinion over this position, the former preferring Black and the latter White.
Their averaged evaluations give Botvinnik a score of just +1, leaving the Soviet patriarch with it all to do in the second game.

Game Two
Alexander Alekhine - Mikhail Botvinnik
French Winawer
1.e4 e6
It will be interesting to see if Botvinnik's favourite French Defence can save him.
2.d4 d5 3.Nc3 Bb4 4.Nge2!?
Alekhine played this gambit line seven times, compared with just one time for the mainline 4.a3.
4...dxe4 5.a3 Be7
Returning the pawn immediately.
6.Nxe4 Nf6
Botvinnik played the text and 6...Nc6 once each, winning with the former and drawing with the latter, so 6...Nf6 is chosen on tiebreak.
7.N2g3
Alekhine played this and 7.N2c3 once each, winning with the former but losing with the latter.
7...0-0 8.c3

This is as far as we can go as Botvinnik never faced 8.c3

Again the engines have a difference of opinion, Stockfish11 favouring Black while Komodo11.01 reckons the position is virtually dead-equal
Their averaged evaluations give Botvinnik a score of +17.5, meaning he wins the match and qualifies for the semi-finals.
Here is the updated tournament bracket.
