Black just played 9...Bh6. Isn't this a blunder?

3 days again.

[b]Solution:

It's not a blunder. Your guys solution was right.

After Bxh6 Qh4+ ___ Qxh6 Black gets control over the dark squares in whites camp. That is why Yasser played Qd2 so after the trade, it is White who has control of the black squares. He accepted the trade but under his conditions.

Um um.... Man it's hard to think under pressure. This is what I got:

Just bumping this up for all to see.

I'm am waiting for chesskid001 and vuelve solution.

Just Vuelve, Chesskid is out of town.

Game 5, Puzzle 3 User solutions:



If 12.0-0 I can think at 2 plans for black:

first: to castle and try to push f7-f5...preatty normal in some variations of King's Indian but it seems now a bit dangerous, as black is not very developed

second(and better in my opinion): is to trade Queens (it is probably forced after Qb6) and after 12...Qb6 13 Qxb6 Nxb6 black has the nice square c5 for his a6 knight which will be developed with threats(for Bd3)...black can continue with 0-0 and f5 in this plan also.



I don't think this is the answer but the move Qh6 stopping black from 0-0 seems good.



If white castles he gives up tempo and allows black to set up his kingside attack with Ndc5 which opens the c8-h3 diagonal for the white bishop. The black queen is already free to attack on the kingside. Also white has some space issues he needs to take care of, his pawns are boxing in his pieces preventing them from working together.
[b]
12- 0-0 would have been a bad move because white doesnt have sufficient protection for the king in the right wing. and the king would have been in direct exposure for the attack only queen in the path to prevent it. Ne2 can be moved only to g3 which again cant be further moved. white square bishop cant control the square on the king's side due to its white's own pawn. the king would have only one square to move. but without castling white can further advance its pawn on the king side with lot of pieces to protect king from check.

[b]Game 5, Puzzle 3. One more puzzle to go after this one. 3 more days again. I found this puzzle really neat. Makes you think how detailed GM's Play is. Reason behind every single move.

Why is 12.0-0 a bad move for White?[/b]

[b]Solution to puzzle 3, Game 5:

12.0-0? Qb6

Which forces a queen trade. Once black trades off queens, black's king is safe and he can use the dark squares to his advantage, namely b6, c5, b4



Every move must have a purpose!

Waiting for Kevin and Chuckorc

Game 5, Puzzle 4 User solutions:

Looking at the position black doesnt have much choices left to move. the pattern of attack of white can be 23 Nb5c7 putting black's queen and rook under attack. then either 23...NxN followed by 24.QxN checkmate. or it can move his queen in which case both of its rook are in trouble. leading to another checkmate.

If black moves his queen to e6 (22...Qe6)then white can easily capture its rook.23 Qxf8+ Be8 orQe8. 24 Rxe6 again putting black under the threat of checkmate. Hence black has no option except to resign.



probably 22...Nxe4 23. Bxe4 Qxe4+ 24. Kf2 Rf7(the rook is hanging) 25 Nb6 threatening Nxd7 and Nxa8 can not be defended



kn f6 holds the pawn and opens a big can of worms with the other knight comming into play and mate soon to come or at least the queen for very little.

[b]White has both knights trained on c7. when the dust clears black will be down a rook and blacks king will have nowhere to run.

Game 5, Puzzle 4(final puzzle). 3 days again. I only need solution from the 4 of you, so if you can get them in earlier then 3 days then I will wrap up this game and start the next one.

After 22.Nb5 why did Black resign. What moves did white have in mind to finish of Black?[/b]

[b]Solution:

White's threat is 23.Qb6+ Kc8 24.Nd6+ winning the queen. Note that the black queen is tied down to the defense of the f8 rook who would fall with check.

If black try's 22...Nxe4 protecting the d6 square
23.Bxe4 Qxe4+ 24.Kf2 Qh4+ 25.Kg1 and the white king escapes.

Black can't meet the threat of, count these:

26.Qxf8+
26.Nxf6
26.Nb6
26.Qb6+

When you have a winning position, there are several ways to win.



GAME SUMMARY

Lessons from the Yasser-Ivanchuk Game

1. Black spend to much time trying to play on the queenside. He didn't think much of white's kingside attack and paid for it.

2. Black's king got stuck in the middle of the fight. This started with black trading of the fianchetto bishop which created weak dark squares around his kindside which white took advantage of by playing Qh6! denying the black king from castling. Trading of a fianchetto bishop is rarely a great idea unless it give you a specific advantage.

Hope you guys enjoyed the game.

I love the Qb6+! Obvious but works. Either blocks it with Nc7 and loses, or plays Kc8 and Nd6# wins and forks the queen!

[b] Game 6. This was originally posted by schakuhr in my thread. There will be 2 puzzles.


[White "J W Schulten"]
[Black: "P Morphy"]
New York 1857

1. e4 e5
2. f4 d5
Falkbeer's Countergambit. Black is going to sac a pawn to get the initiative.

3. exd5 e4
The black pawn puts alot of pressure on white's position here. It's hard to remove and keeps white from developing like Nf3.

4. Nc3 Nf6
5. d3?!
Attacks the pawn on e4 for a second time, but this allows black to pin the knight on c3.

5. ...Bb4
6. Bd2 e3!
Black sacs another pawn to disturb white's development and get an open e-file against white's king.

7. Bxe3 0-0
8. Bd2
Prevents a pin after Re8, and takes the pin off Nc3. White can then place the knight somewhere on the e-file to block the rook.

8. ...Bxc3
black wants to prevent the knight from doing so ofcourse.

9. bxc3
If 9. Bxc3, then 9. ...Nxd5 and white loses another pawn (Nxf4), after which black has a big lead in development.

9. ...Re8+
10. Be2 Bg4
White is terribly cramped now. He should play 11. h3 and try to get looser, but instead he tries to keep his material advantage, as compensation for his positional disadvantage. This is even worse though.

11. c4?! c6!


12. dxc6?
Terrible. This helps black to complete his development. Again 12. h3 would have been the best.

12. ...Nxc6
Threatening Nd4, and white can't do anything anymore to stop this.

13. Kf1 Rxe2
Wins 2 pieces for a rook, without losing the attack.

14. Nxe2 Nd4
15. Qb1 (white can't do anything anymore) Bxe2+
16. Kf2
After 16. Kg1, black wins with 16. ...Nxc2!, threatening Qd4+ and mate. 16. Ke1 loses to 16. ...Qe7, followed by a deadly discovered check.

16. ...Ng4+
17. Kg1
Or the artistic mate 17. Kg3 Nf5+ 18. Kh3 Nf2#. Also, white is mated soon after 17. Ke1 Qh4+! (this is necessary, white has to move g3, and then square f3 isn't guarded anymore.) 18. g3 Qe7 with the inevitable threat Nf3#.
17. ...Nf3+
18. gxf3 Qd4+
19. Kg2 Qf2+
20. Kh3 Qxf3+
21. Kh4 Ne3
22. Rg1 Nf5+
23. Kg5 Qh5#

Just like the first game, white lost because a lack of development, and he only cared about material.

Waiting for vuelve.

Game 6, Puzzle 1 User Comments:

Probably 5 Bc4 ...6. Nge2 and 7.0-0 is a better development plan

Bb5 with check looks by far the best to me. Black can not just move c pawn froward and the black bishop stopping check is not bad becuase the knight is already guarding that square.


I would continue my development and move 5.Qe2. which then allows 6.d3.

[b]I think 5 Bc4 or Bb5+ would have better alternatives for white's further advancement. followed by d3. but i dont see that much problem with the move 5 d3 either. 5 d3 Bb4 6Bd2 e6 and so on.
