Dr. Siggy: Quoting F. Reinfeld, "Tarrasch's Best Games of Chess", New York 1946, pp. 269-72:
[Introduction:] "Tarrasch considers this the finest game of the match. It is an impressive example of what the two bishops can accomplish in a fairly open position."
[About 8...Nf4(!?):] "[...] the knight tour is attractive, as it leads to an attack on the king's pawn without loss of time."
[About 11.Bd3:] "Apparently very powerful, for after the following exchange, Black's pawn formation is in a pitiable state. Black's two bishops and open lines are more than ample compensation [...]"
[About 13...Ba6!:] "Far from being despondent over the wretched state of his pawn position, Tarrasch sets about making good use of the two bishops. The text is an excellent beggining, as White is prevented from castling."
[About 16...0-0:] "Tarrasch sees that the f-file will be far more useful to him than the e-file. In addition, the removal of the king makes it possible for him to utilise the e-file at just the right moment."
[About 17...d6!:] "The combination of the two bishops' pressure with and the e-pawn's difficult position makes White's game unbearable [...]"
[About 21.c4:] "The attempt to maintain material with 21.Bxe5? would lead to a débâcle after 21...Re7 22.Nxc7 Rd8+ 23.Kc1 Bb7 24.Bf4 Be3+ 25.Bxe3 Rxe3 and the knight is lost (Tarrasch)."
[About 24...c5!:] "A move with two functions. It reinforces the king's bishop's position and opens an effective diagonal for the other bishop."
[About 28.Nc3:] "Black was threatening to win the bishop with ...Bb2+. The enormous power of Black's position is illustrated by the following piquant variantion given by Tarrasch: 28.Bc1 Red8 29.Tdf1 (...Bg1+ was threatened) Ba1+! 30.Ke3 Rd3+, winning the knight."
[When White resigns:] "[...] A fine demonstration of the bishops powers."
