A strange coincidence in the Reti - Euwe match.
We have just seen Euwe beat Reti's Queen with a two Rooks
In two previous games from this match Reti played the double Rook sac twice.
(That is saccing 4 Rooks) and won two superb games.
Then came the above game.
Euwe decided not to take Reti on in theorectical debates hence the 1.e4 c6 2.b3 opening.
After this match and possibly influenced by the play of Euwe in this game.
Reti changed his style. Four years later in New York 1924 he beat Capablanca
with the stem game of the 'Hyper-moderns'.
So you could say Euwe (along with Reti, Breyer, Tartakower and of course Nimzovitch)
took chess in a new direction.
You will see that Reti was a master tactician first, and hypermodern later.
Some try to skip the master tactician bit and try to play like Reti without
ever really understadning why they keep getting beat.
They fall for two move tricks and miss the chance to go tactical when
it favours them.
The first double Rook sac is quite brilliant and well worth understanding.
It was responsible for throwing Euwe's 9th move (Nxd4) into the opening theory dustbin.
The second and we see Reti playing a Staunton Gambit.
