1. d4 d5 2. c4 e6 3. Nc3 Bb4 $5 {This obscure move may not be as bad as it
seems. The motivation for playing it is to allow a Ragozin QGD player to avoid
the exchange varition. This allows him to play fewer lines of the NID and
vastly simplifies his repertoire against the English which he can now meet
with 1.c4 e6 2.Nc3 d5 3.d4 Bb4.} (3... Nf6 4. cxd5 exd5 5. Bg5 Bb4 {As
discussed by Flear in Dangerous Weapons. If black is aiming for a mainline
Manhattan position in the Ragozin, it seems to give white a great position.} 6.

the danger of the pin on f6. Compare to the analagous 3...Bb4 4.Qb3 without
the pin.}) 6... Nbd7 7. Bd3 c5 8. Nge2 $3 {Black's plan in the Manhattan of c4
and queenside expansion is too slow when white is poised to break with f3/e4
very quickly.}) 4. a3 (4. Nf3 Nf6 {Transposes to the Ragozin}) (4. cxd5 exd5 5.

4. Qb3 $6 {This not as effective as the analgous move in the exchange with Bb4
where white has black's knight pinned on f6. Black develops with tempi due to
the pinned knight, weakness on d4 and the misplaced queen.} c5 5. cxd5 (5. dxc5
