 000000                               000010Capturing with the Queen       000011prevents the isolation of      000012Black's Queen Pawn resulting   000013from :                         000015   4 ... KPxP                  000016   5 PxP                       000020When Black recaptures with the 000021King Pawn, it opens a diagonal 000022for the Queen Bishop           000030A good first move.  White      000031starts by controlling the      000032center of the board.           000040The first move of the French.  000041Black intends on advancing     000042the Queen Pawn, attacking      000043White's King Pawn and trying   000044to control the center also.    000050White continues to control     000051more of the center.            000060Black just changed the game    000061from a King's Pawn to a        000062Queen's Pawn opening.          000070The first move of the Tarrasch 000071variation of the French.  This 000072move protects the King Pawn    000073without N-QB3.  N-QB3 would be 000074subject to the pin resulting   000075from 3 ... B-N5.   Now if the  000076Black bishop moves to N5, the  000077QBP can block.  The Knight     000078move does however block in the 000080Black develops a piece and at  000081the same time attack's White's 000082Queen Pawn.                    000090Black attack's the King Pawn.  000091Unfortunately White can make   000092the Knight move again by       000093pushing the King Pawn to K5.   000079Queen Bishop.                  0000a0Black continues to attack the  0000a1center almost at will.  The    0000a2White Queen is blocked and the 0000a3Knight on Q2 is not attacking  0000a4Black's Queen Pawn.            0000b0White can continue with the    0000b1following set of moves :       0000b3   7  O-O   ...                0000b4   8  Q-K2  ...                0000b5   9  R-Q1  ...                0000b6  10  N-N3  ...                0000b8which should win back the      0000b9pawn with a strong position.   0000c0White aims to isolate Black's  0000c1Queen Pawn.                    0000d0Usually a simple check like    0000d1this can be discounted.  But   0000d2White is really trying to      0000d3isolate Black's QP.  Once it   0000d4has been isolated, White will  0000d5simplify the position by trad- 0000d6ing pieces.  If this happens,  0000d7Black goes into the middle and 0000d8end games with a defective     0000d9pawn structure.                0000e0Still headed for an end game   0000e1that has Black stuck with an   0000e2isolated Queen Pawn.           0000f0Black is almost forced into    0000f1this move.                     0000f3If 6 ... B-K2  then            0000f4   7 PxP       and White has a 0000f5               Pawn plus.      0000f7If 6 ...   B-K3 then White has 0000f8   7 KN-B3 ...  followed by    0000f9   9 N-N3  ...                 0000f:  10 QN-Q4 ... with pressure   0000f;          on Black's QN and QB 000100White enjoys a lead in         000101development and Black has an   000102isolated Pawn.  Black on the   000103other hand has a fairly free   000104game, not much in the way of   000105compensation.                  000110White can now continue with    000112  10  QN-Q4  ...               000113  11  B-KB4  ...               000114  12  O-O-O                    000116White can then pile up on the  000117isolated Queen Pawn with a     000118good game.                     000018However, the Queen has been    000019prematurely developed.  White  00001:can chase the Queen obtaining  00001;a lead in development.         000130Black can avoid exchanging     000131Queens with this move, but it  000132usually leads to the loss of   000133Black's QBP.
