A tournament game I finished today. Any comments?
 
I would not mind comments on the game I posted vs the Tournament Chess AI either.
 
1.e4 e5
2.Qh5

This can lead to a quick mates against an unwary opponent, but is not good opening practice because it is too easy for black to force the queen to move several more times.

Nc6 should be played first to protect the e-pawn. Then the queen can be driven back.

Lots of blunders on both sides. White started off with a big advantage, then black was ahead, and then white came back. Both players need to work on looking at how the move they're about to play changes the other player's opportunities, and on recognizing pieces that can be won with a simple capture (en prise).

BTW, which side were you?
 
Here's a game I lost against the Tournament Chess game AI (I'm black):

1. d4 e6
2. c4 Bc5
The most important thing for you to focus on is not hanging pieces (moving to or leaving them on squares they can be captured). I've noticed this in several games.
3. dxc5 Nf6
4. e4 Nxe4
5. Qg4 0-0
6. Qxe4 d5
7. cxd6 cxd6
8. Bd3
Having a bishop and queen on the same diagonal is a danger sign, especially this diagonal with the queen in front. And even more so if you don't have a knight on f6.
There are at least 5 moves here which can prevent the mate, though only 3 prevent major additional material loss. See if you can find all of them.
9. Qxh7# 1-0

White - I won
 
I dropped my 2nd game vs. ildottore.

http://www.chess.com/echess/game.html?id=19877211

Any commentary welcome & appreciated.
White's move 17 was the first move that wasn't "book". The database game continued 17. Qb5 and was won by black, but with only the one game it's hard to say whether that is accurate. It looks like the move 8 choice between ...Ng8 and ...Nd5 was the pivotal point for this variation.

Some alternatives that my engine kicked out, at 45 seconds per move:
18...Qe6
20...Rxb8
21...Rc8 (not much improvement)
22...Rc8 (1/2 pawn difference)
 
In the the fourth game I was once again black, that's three times out of four so far. I decided to try the Dragon for the first time (ever). He played very defensively and offered a quick draw. I couldn't see that I had anything constructive to do so I agreed.

The once chance I had to mix it up was with 16...Ng4 17. Bd4 e5 I did see this during the game but it looked complicated and I wasn't sure it was better for me. It opens a hole on d5, makes the d-pawn backwards and later isolated and might open the f-file for his rook. I did not evaluate this as better for me but the computer seem to think it was somewhat better for white.

The fifth game I met the highest rated player in our group. He was a young player that was rated over 1900 not long ago. He won every game convincingly including this one. I played unusually badly for some reason.

Time for game 6. This was without a doubt the hottest day to date. In fact, it was so hot they had to go get fans to put up for the highest group. For us in the lower groups there were no fans and probably over 35 degrees centigrade. With the juggernaut I faced in the last round ending up with 7/7 and no way for me to reach 6 points (80%) I could no longer advance to class II and so this game was meaningless apart from rating and placement in the group.

My opponent however had only one loss to the juggernaut and could still reach 6 points and advancement if he won today. So I decided to take no chances trying to get a balanced position where he had to take risks to win perhaps giving me some chances. For this reason I decided to avoid the sharp dragon variation with a free kingside attack for white and go with something else. Also, being so terribly hot, I moved much more quickly than I normally do trying to get out of the heat as fast as possible.


1. e4 e6 2. d4 d5 3. Nc3 Nf6 4. Bg5 Be7 5. e5 Nfd7

Needing to win I thought he would play the gambit h4 here. He thought about it but didn't know the variation very well.

6. Bxe7 Qxe7 7. f4 O-O 8. Nf3 a6

I guess c5 is the normal move. I have been burned by Nb5-d6 before though and decided to rule that possibility out.

9. Bd3 f6

White was threatning Bxh7+ followed by Ng5+ and Qh5.

10. exf6 Nxf6 11. Qe2 Nc6

Qe2 looked a bit unusual to me. This turned out to be the first game ever I played the French defence without ever playing c5. I could have played it here but I wanted to use the placement of his queen to quickly get his light squared bishop. Also, since I'm tactically challenged, I wasn't 100% sure there were no tricks involving Nxd5, Nxd5, Bxh7+. After Nc6 the queen is guarded which allow exd5.

12. g4 Nb4

We were both of the opinion that Nxg4, Bxh7+, Kxh7, Ng5+, Kg8, Qxg4 was okay for him. This turned out not to be the case since if you are good at calculating (which I am not, that's pretty much the limit of my visualisation ability) you see that e5 reveal an attack on the queen and after Qh5, exd4+ black can then play Bf5 to avoid the mate.

13. Ne5 Nxd3+ 14. Qxd3 Nd7 15. Qg3 Nxe5 16. fxe5 Qg5

During the game and during our analysis we considered this to be a small mistake since it doesn't seem to accomplish much and loses a tempo to Bd7 right away. Interestingly the computer has Qg5 as the best move up to about 11/12 depth and then it sinks slightly but remain an okay move.

17. Ne2 Qe7 18. O-O-O Bd7 19. g5 Rf5 20. h4 Raf8

Taking control of the c-file. I still have my sub-optimal bishop but felt I wasn't in too bad shape here.

21. Qb3 b6 22. c3 Be8 23. Rdg1 Rf2

During the analysis he said he had simply missed this move.

24. Qd1 Bh5 25. Re1 Rg2 26. Rhg1 Rh2 27. Rh1

This is the first game where I really physically felt the heat affect my game. The entire time I had been playing very fast hoping to get out of there. Here I missed a very simple win with Rxh4 simply picking up both pawns. After Qd2, Rxh1, Rxh1, Bxe2, Qxe2, Qxg5+ it's a trivial win.

27...Rg2 28. Rhg1 {draw agreed} 1/2-1/2

I was happy to get the draw and get out of there. Since the win hadn't ment too much I wasn't too disappointed that I missed it.

Good job Panzar, shame you missed the win but nice game anyhow :)

Commentary really helped follow the game, would have been oblivious to the whole bxh7 threat - very instructive, thank you!
 
We had some rain in the moring so it wasn't as hot the last round. The temperature did climb during the day back to some 30 degrees but it wasn't near as hot as the previous few days. I played the lowest rated player in the group with white so I was determined not to get another draw but to play all out for the win.

1. e4 d6 2. d4 Nf6 3. Nc3 g6 4. Be3 Bg7 5. Qd2 h6 6. h3 Nbd7 7. O-O-O b6 8. f4 Bb7 9. e5 Nd5 10. Nxd5 Bxd5

Protecting the a-pawn isn't strictly neccessary since Bxa2, b3 wins the bishop but I figured I wanted the king on b1 anyway.

11. Kb1 a6 12. Bd3 c5 13. c3 c4 14. Bc2 b5 15. Rh2

Gets out of the pin and also might help defend the kingside along the second rank at some point.

15...a5 16. f5

On gxf5 I had planned exd6, e6, g4 which looks like it opens black up a bit but the computer think is no big deal.

16...g5 17. exd6 exd6 18. Re1 O-O 19. h4 f6 20. hxg5 fxg5 21. Nh3

I am not really getting anywhere. In fact, I'm now even slightly worse. Fortunately my 1200-rated opponent now played a howler of a move.

21...Bf6 22. Nf2 Kg7 23. Ng4 Rh8 24. Reh1

Finally I have something to work with. But I was still worried about his counterplay with b4.

24...a4

Another really terrible move allowing me to close the queenside.

25. a3 b4 26. cxb4 Qc7 27. Rxh6 c3

If he was this desperate to open the queenside he should have played 24. b4 instead. A few paws up I won the endgame easily.

28. Qxc3 Qxc3 29. bxc3 Bxg2 30. Rxh8 Rxh8 31. Rxh8 Kxh8 32. Bxa4 Be4+ 33. Bc2 Bxc2+ 34. Kxc2 Bd8 35. Kd3 Kg7 36. d5 Be7 37. a4 Nb8 38. Bb6 Kf7 39. b5 Nd7 40. Bd4 Ke8 41. f6 Bd8 42. Ke4 Nf8 43. Kf5 Nh7 44. Kg6 Nf8+ 45. Kxg5 Kf7 46. Kf5 Nd7 47. Nh6+ Kf8 48. Ke6 Nc5+ 49. Bxc5 dxc5 50. Ng4 c4 51. Ne5 Ba5 52. Nd7+ Kg8 53. f7+ {black resigns} 1-0

So the end result was 4,5/7 which gave me third place in the group. Not that great but also not as disasterous as last year. I'm playing both weeks this time so I'll get a new chance starting tomorrow.

Game from me in the team match vs the Supreme Pawns. Quick attack with a double pin to his king :)

In a hopeless endgame he then blundered so I could set him mate without the tedious pawn push
