1. d4 d5 2. c4 c6 3. Nf3 Nf6 4. Nc3 e6 5. e3	White have to consider also Bg5, although that is the line that I usually use myself.
	2 comments fatcat2 (1200) on 16-Apr-09: 5.Bg5 retains flexibility, developing the bishop on an active square outside the pawn chain. rjacobs (1760) on 20-Apr-09: but 5.Bg5 also leaves the dark squares on the Queenside vulnerable to attack, especially after a subsequent Pe3. In various QGD/Slav openings, I often regret playing Bg5.


5... Nbd7 6. Bd3 dxc4 7. Bxc4 b5 8. Bd3 a6	So far all is theoretical.
	2 comments fatcat2 (1200) on 16-Apr-09: White should be looking to control Black's queenside pawn expansion, which is pressing on his light-squared bishop and queenside knight. vincerino (1200) on 17-Apr-09: 8. ... Bb7 looks a little more sound than a6


9. e4	Is it a must now? Usually it is better to castle first. I think that it is not so bad, as the black king is not castled yet and white can attack in the middle.
	1 comment vincerino (1200) on 17-Apr-09: 9. a4 is also a consideration


9... c5	Black is not yet developed.



10. e5	It is too soon to break through. white had to castle first and move his rook to e1. if black would take on d4 than white should have taken with the knight and he controls the center well.



10... cxd4 11. exf6 dxc3 12. fxg7 Bxg7 13. Qc2	black is left with a pawn up in all the exchanges and he got the h8-a1 diagonal.
	1 comment fatcat2 (1200) on 16-Apr-09: And he retains his powerful pawn chain on the queenside, albeit slightly separated, while White's has been obliterated.


13... Qa5	wants to take on b2.



14. O-O	a must play move.



14... Bb7	black should have played here 14... Nc5 and I dont see how white avoid exchanging the bishop with the knight.



15. Ng5 Rc8	one would think that black has the advantage. by letting white to play Ng5 black is in defense and not attack. his kingside is very weak and wont last long in the batlle.
	1 comment fatcat2 (1200) on 16-Apr-09: Perhaps 15...b4, shoring up the c-pawn and discovering an attack on White's knight.


16. Qe2	the queen is now setting up the final attack.



16... h6 17. Nxe6	of course. black is falling apart.



17... fxe6 18. Qxe6+ Kd8 19. Re1	now we see how not organized are black pieces.
	1 comment fatcat2 (1200) on 16-Apr-09: And how exposed is Black's king. An excellent game for demonstrating the importance of castling.


19... cxb2 20. Bf4	mate on e7...



20... Rc6	only move.



21. Qe7+ Kc8 22. Bf5	mate on d7... the pair of bishops are working great together.
	1 comment fatcat2 (1200) on 16-Apr-09: While Black's bishops, while nominally fianchettoed with good central control, are badly coordinated and can do nothing to help.


22... Rd8	only move.



23. Rab1 Bf8 24. Bxd7+	mate in 4.



24... Rxd7 25. Qxf8+ Rd8 26. Qf5+ Rd7 27. Re8+	pay attention to the final position. it looks like a problem solved.
	2 comments ruachessnut2 (1200) on 17-Apr-09: Did Black resign to avoid 27...Qd8 28. Rxd8 Kxd8 29. Qf8#? You rarely a mate followed by a question mark! stylas (1766) on 17-Apr-09: Black could have avoided defeat by playing 25 Qd8. The obvious 26 Re8... (would not win the white queen and in fact would end in defeat for white) Rc1+, 27 Rxc1... bxc1=Q+, 28 Bxc1... Rd1# - mate for black! Had black moved 25 Qd8 white would be forced to swap queens and could gain a pawn up by taking black's b2 pawn
