Nxe4 {?! Tartakower: The only correct reply is 5...Qe7.} 6.Nxe4 Nxb5 7.
Nxf7 Qe7 {Tartakower: If 7...Kxf7? 8.Qh5+, followed by 9.Qxb5.} 8.Nxh8 
Qxe4+ 9.Kf1 {Tartakower: The first surprise. After 9.Qe2 Qxe2+ 10.Kxe2 d5,
etc., Black would have an easy task. *** Reti: The right continuation. 
After the exchange of queens Black will capture the knight on h8 for an 
advantage in the endgame.} 9...Nd4 {Tartakower: Or 9...g6 10.d3 Qe5 11.Qf3
Qxh8 12.Bg5 Nd4 13.Re1+ Ne6 14.c3, and White holds the reins. *** Reti: 
Better was 9...Qf5, neutralizing the threat 10.Qh5+ and immediately 
leaving the dangerous e-file.} 10.d3 Qf5 11.h4 {! Tartakower: The second 
surprise. Not only does White's king obtain a flight square, if it should 
be wanted, but his h-pawn becomes a trenchant weapon, whilst his 
"motorized" rook on h1 threatens to get into action via h3.} 11...b6 {
Reti: With the idea of ...Bb7 and ...O-O-O, but this plan is unfeasible. 
Better is 11...d5. *** Tartakower: He refrains from playing 11...d5 in 
order to be able, later on, to obstruct the open e-file by ...Ne6.} 12.Bg5
{Tartakower: Supported by the advanced h-pawn, the white bishop is now 
comfortably settled in the hostile camp. If now 12...h6, he replies simply
13.Be3, followed by 14.h5 and 15.Ng6, saving the knight.} 12...g6 13.Qd2 
Bg7 14.Re1+ Ne6 {Tartakower: Or 14...Kf8 15.h5 Bxh8 16.hxg6 Qxg6 17.Qf4+ 
Kg8 18.Rh6, winning.} 15.h5 gxh5 16.Rxh5 Bxh8 {Tartakower: Or 16...h6 
17.Rxh6 Bxh6 18.Bxh6 Qh7 19.Qg5 Qxh8 20.Qh5+ Ke7 21.Bg5+, winning the 
queen. After the text move, Black has become the stronger in material, but
the disorganized position of his pieces will cause his ruin.} 17.Qb4 c5 {
Tartakower: After 17...d6 18.g4, and if 17...Kf7 18.Qe7+ Kg8 19.Rxe6! dxe6
20.Bh6 wins.} 18.Qh4 Kf7 19.Bd8 {!} 19...Qg6 20.Rh6 Qxh6 {Reti: If 
20...Qf5 21.g4, and White wins.} 21.Qxh6 Nxd8 22.Qh5+ 1-0
