white to weaken your pawn structure if he wishes with Bxc6+. 
In this case, you don't have to allow the weakening. 
4. ... Nge7 develops a piece while at the same time maintains 
your pawns' integrity. Notice if white plays complacently 
with 5. O-O a6 6. Ba4? b5 7. Bb3 c4 wins a piece. Notice 
white couldn't take advantage of the pin that you walked

Since this bishop has already moved, simply castling king-side 
with O-O was very good. Why can't checkmate with just a queen. 
She needs support. } 10. Qa4 Bb7 { Again, an unnecessarily passive piece placement. The most 
aggiessive post for this piece is a6, and you could put it 
there if you defended your c-pawn with ...Qb6 instead. } 11. Qb3 O-O { The losing move. Much stronger is ...Rb8!, developing your 
rook, defending your bishop. This even sets up a sneaky trap.

expanded in the center by playing ...e5. } 18. Qd3 { White is playing well...when ahead in material, trade 
material. This makes white's piece advantage even stronger. } 18... Rfc8 19. Qxg6 hxg6 20. Re1 e5 { This loses a pawn. ...Kf7 was to be preferred. } 21. dxe5 f5 { This concedes an unopposed (passed) pawn to white. As

move was -- what is their idea? Are they threatening anything? 
Also, try to place your pieces in the best places. To ccompare 
where good posts are, just compare how many moves your piece 
would have at the various squares. Whichever gives your piece 
the most mobility, is the best square. NOTE: You will have to 
balance good placement with the piece's safety. If pawns can 
push your piece around, then that's not a very good square 
either. Otherwise, you did fairly well with the resources 
you had available. } 46. c5 ?

{ 00002.4.7 Analyzed by National Master Corey Russell } 1. e3 c5 2. Bc4 e6 3. Nf3 Nc6 4. Bb5 d5 { This does put a foothold in the center, but this allows 
white to weaken your pawn structure if he wishes with Bxc6+. 
In this case, you don't have to allow the weakening. 
4. ... Nge7 develops a piece while at the same time maintains 
your pawns' integrity. Notice if white plays complacently 
with 5. O-O a6 6. Ba4? b5 7. Bb3 c4 wins a piece. Notice 
white couldn't take advantage of the pin that you walked 
into after playing ...d5. } 5. Ne5 Ne7 6. Bxc6+ Nxc6 7. Nxc6 bxc6 8. Nc3 Be7 { A little passive. Why not the more aggressive ...Bd6? } 9. Qg4 Bf6 { Definitely dubious. This bishop needs to defend the c5 pawn. 
Since this bishop has already moved, simply castling king-side 
with O-O was very good. Why can't checkmate with just a queen. 
She needs support. } 10. Qa4 Bb7 { Again, an unnecessarily passive piece placement. The most 
aggiessive post for this piece is a6, and you could put it 
there if you defended your c-pawn with ...Qb6 instead. } 11. Qb3 O-O { The losing move. Much stronger is ...Rb8!, developing your 
rook, defending your bishop. This even sets up a sneaky trap. 
If 12. O-O? Ba6 13. Qa4 Bxf1 wins material for black. } 12. Qxb7 Qe8 13. Na4 Be7 14. d4 cxd4 15. exd4 f6 16. O-O Qf7 17. Qb3 Qg6 { Notice that if you played ...Bd6 earlier, you could've 
expanded in the center by playing ...e5. } 18. Qd3 { White is playing well...when ahead in material, trade 
material. This makes white's piece advantage even stronger. } 18... Rfc8 19. Qxg6 hxg6 20. Re1 e5 { This loses a pawn. ...Kf7 was to be preferred. } 21. dxe5 f5 { This concedes an unopposed (passed) pawn to white. As 
unpleasant as it was, ...fxe5 was to be preferred. } 22. e6 Re8 23. h3 Rac8 24. Bd2 c5 25. Re5 Rcd8 26. Ba5 Bf6 27. Re2 Rc8 28. Bc3 d4 { Good, avoiding exchanges when behind in material. This is 
black's best chance. } 29. Bd2 g5 30. c3 g4 31. hxg4 d3 32. Re3 Rcd8 33. gxf5 Bg5 34. e7 Bxe7 35. Rxe7 { Strong move by white. White is trading more & more material...

and forces black to resign. } 42... g5 43. c4 Rd4 44. Rd2 Rxd3 45. Rxd3 Kxd3 46. c5 { So in conclusion, always look at what your opponent's last 
move was -- what is their idea? Are they threatening anything? 
Also, try to place your pieces in the best places. To ccompare 
where good posts are, just compare how many moves your piece 
would have at the various squares. Whichever gives your piece 
the most mobility, is the best square. NOTE: You will have to 
balance good placement with the piece's safety. If pawns can 
push your piece around, then that's not a very good square 
either. Otherwise, you did fairly well with the resources 
you had available. } ?

opening development of black's dark squared bishop. } 6. Bf4 { ? Definitely bad. White should try to castle as soon as 
possible. Also, in the opening, it's best to develop with 
attack. 6 Bc4! would be the way to do it (threatens black's 
knight at d5). After this, black will get an advantage. } 6... Nc6 7. Qd2 h6 { Black's first slip. Black can win a pawn, starting with 
7. ... Nxf4 8. Qxf4 Qc7 9. Nf3 f6. Notice white can't take 
the black pawn on f6 because that would expose white's queen 
to attack by the black queen. White's king pawn is what is 
called a pin. } 8. Bb5 Be7 9. Bxc6 dxc6 { When having the option, it is generally better to capture 
TOWARD the center of the board. Hence bxc6 is preferred. 
In addition, this would give black an excellent post for 
his queen bishop on a6. Notice that black's queen bishop 
doesn't even move this game! If white does proper defence, 
this lack of post for thie bishop could've meant a loss for 
black. } 10. c4 { Very bad. White needs to get pieces out immediately. Nf3 
is called for. } 10... Nxf4 11. Qxf4 Bg5 12. Qf3 Qa5+ 13. Nc3 { White misses a strong defence: Qc3! That would a) defend 
the e-pawn b) block the check c) threaten black's queen. 
Try to look for moves that do more than one thing at once, 
if possible. } 13... Qxe5+ 14. Nge2 O-O 15. Ne4 { Remember: Using ALL of your chessmen is always more effective. 
White could've played the correct O-O, and after Rad1, Rfe1, 
ALL of his pieces would be active, while black has a hemmed 
in light-squared bishop. White would have real chances to 
save his game, despite being a pawn minus. Instead white 
gives up his b-pawn for free. } 15... Qxb2 16. O-O Be7 { Good. This preserves the bishop pair. Bishops control more 
squares on an open board. You could check this for yourself. 
Put 2 knights on an empty board in the center, and they can go 
to 16 squres. Put 2 bishops in the middle, 
and they can go to 26 squares! } 17. g4 f5 18. gxf5 exf5 19. Rab1 Qe5 20. N4g3 g6 { Better is 20. ... f4, because this would deny white a square 
for his Knight at f4, in addition open up the h3-c8 diagonal 
for black's bishop. With the text, white can play 21. Nf4 Qf6 
22. Re1 g5 23. Ng6! Qxg6 24. Rxe7, with chances for white to 
survive. } 21. Qd3 Rd8 22. f4 { ?? Misses black's in-between move. Black should win easily now. } 22... Qc5+ 23. Kg2 Rxd3 24. Rbd1 Qxc4 25. Nc1 Qc2+ 26. Nge2 Rxd1 27. Rxd1 Qxd1 28. Kf2 Bc5+ 29.

have gotten your rook & bishop active, you win would have been 
sure. As it was, white had many chances to get in the game. } 33... Qg4# ?
