comment: The right rook: after the capture on b3, the other rook is well-placed on the a-file.
context: 1. e2e4  1... c7c5  2. g1f3  2... b8c6  3. b1c3 This move is a good option if you don't want to get into a battle in the Sveshnikov Defense. 3... g7g6 Black chooses the Accelerated Dragon. 4. d2d4  4... c5d4  5. f3d4  5... f8g7  6. c1e3  6... g8f6  7. f1c4  7... e8g8 Because the pawn remains on d7, Black has better chances if we compare the position with a normal Dragon. 8. c4b3  8... f8e8 A somewhat \"mysterious rook move\" as Nimzowitsch phrased a long time ago, but this is well known to opening theory. The rook can be useful to support a plan with e6-d5 or even d5 immediately. 9. e1g1  9... d7d6 Threatening ...Ng4. 10. h2h3  10... c6a5 Black is happy to remove the dangerous bishop from the board. 11. d1e2 Finishing development. It's hard to say if the queen is better placed on e2 or on d2. 11... b7b6
