The downside of black's defense is that they don't fortify their center with a pawn. White takes advantage of this by ridding black of their center pawn and playing to get a pawn duo in the center.} Nxd5 ({ Capturing with the queen is no better, it is vulnerable to tempo moves.} 3... Qxd5 4. Nc3 {developing with a tempo against the queen, threatening to play e4 on the next move} Qa5 {pinning the knight, the only way to slow down e4} 5. Bd2 $1 {but now white unpins, and takes aim at the queen renewing the idea to play e4, white already has a large advantage} Qb6 {again slowing down e4, this time with an attack against white's pawns, but white need not worry, the black queen is misplaced and taking the b pawn would only make things worse...} (5... c6 6. Nf3 $16 {cutting out ...e5 and white will play e4 next}) (5... e6 6. Nf3 $16) (5... Bf5 $6 6. e4 $1 $18) 6. e3 Qxb2 $4 {was tried agains't me once, the game was over quickly...} (6... c6 {is better but doesn't give black much hope of equalizing either} 7. Bc4 Bf5 8. Nf3 Nbd7 9. O-O e6 10. Qe2 $14 {and white stood better with their stronger center as long ago as 1-0 (26) Flohr,S-Hasek, J Prague 1930, there may even have been more accurate ways for white to get a larger advantage, but this is simple.}) 7. Rb1 Qa3 8. Nb5 $18 {1-0 (8) Kestenberg,T-NN chess.com blitz}) 4. Nf3 $1 {An accurate move, white cuts out any of black's ideas to play ...e5, and threatens to play e4 putting a duo of pawns in the center} (4. e4 {is also possible} Nf6 5. Nc3 {however black can now try to reach a slightly inferior endgame with...} ({is another way for white to get an advantage, as played by WCH Anand} 5. f3 $14 Nc6 $6 6. Be3 e6 $6 7. Nc3 Be7 8.

Nf3 $1 (6. dxe5 Qxd1+ 7. Kxd1 Ng4 8. Nd5 { even here black has trouble surviving ½-½ (56) Steinitz,W-Gunsberg,I New York 1891}) 6... exd4 7. Qxd4 Qxd4 8. Nxd4 $14 {0-1 (25) Zimmermann,O-Alekhine, A Basel 1925}) 4... -- {here black has tried a handfull of moves but none of them offer a solution to their problems as we will see in the following example games} (4... g6 {this is like a bad version of a grunfeld defense, white gets a strong center and black's counter play to attack it is minimal} 5. e4 {white takes over the center} Nb6 6. h3 $1 {a useful prophylactic move, white this plays against the Bc8 and prevents it from pinning the knight to keep the d4 pawn stable} Bg7 7. Nc3 O-O 8. Be2 Nc6 9. Be3 $14 {white has a stable advantage in the center 1-0 (39) Levenfish,G-Lilienthal,A Moscow 1948 URS-ch (Ftacnik,L)}) (4... Nc6 {this is very well met with the natural move} 5. e4 Nf6 (5... Nb6 6. d5 $16 {is awkward for black's knights, and highlights the downside of the marshall defense, developing knights without a pawn in the center to prevent the opposing pawns from advacning}) 6. Nc3 {white has ideal development and black has no center, white's advantage is clear. In a blitz game I once faced...} Bg4 (6... e6 {looks more reasonable, but not palatable after simply} 7. Bd3 Be7 8. O-O O-O {white gets good attacking chances on the kingside by grabbing space with...} 9. e5 $16 {as in 1-0 (38) Karpov,A (2674) -Lettowsky,M Vienna 2005}) 7. d5 $1 {chasing back the knights} Ne5 $2 {the knight should have gone back as now white has the shot...} (7... Nb8 $16) 8. Nxe5 $3 {offering the queen to win the game!} Bxd1 9. Bb5+ {this is the point, black's king has no flight squares} c6 (9... Nd7 10. Bxd7+ Qxd7 11.
