HCC Saturday August 11, 2007

I played in the August 11 HCC Saturday Open and finished second with 2.5 points in three rounds. The tournament crosstable will is here.

I have modified my ISAM method to comply with new (as of Jan 1, 2007) USCF rules that the player make the move on the board before recording it on the scoresheet. Changing a 20 year habit proved not to be too difficult but I think there were times I played a little more impulsively than usual.

You can play over all of my games from that event in your browser from the link in the sidebar HCC August 11, 2007 under games archive. The positions below are from those games. So if you are interested in puzzles try these before playing over the games (where all is revealed).

This USCF Press Release lists the top World Youth Qualifiers. Number one for Girls under 8 is Evan Xiang at 1484. My first round opponent.

In this position Evan can win a piece. Do you see how? She did. Black to move:


Coming back from a piece down I see a chance for a draw. Do you? Do you see what I didn't see? (Fritz did). White to move:


My game with Alan Rodenstein was largely "positional" or perhaps "anti-positional". In any case, it may threaten my claim that chess is all tactics. I played the Moron Defence.

The game ends with a "subtle positional manuever" :-). Black to move:


In my game with Will Clayton I was in a swashbuckling mood and offered a Danish Gambit but he didn't want to go there. The game continued in gambit style. In the opening, the center, piece development and king safety are important concepts to keep in mind. This game illustrates their importance through the endgame.

White can put a big hurt on black here:


How does White continue:


I can't believe that I missed this shot for White:


Compare White's rooks to Blacks. How to turn the development advantage into something more concrete and lasting? White to move:

Nice idea to post some problems from your own games.

Ok, here are my ideas about the positions and questions (dont know if you wanted feedback of that sort, but here it is anyway :) ):

a) 1...Bxe5, if then 2.Qxe5 there is 2...Qxh4, so black is one knight in front no matter whether white retakes or not.

b) At first I thought about 1.qf6 thinking there was no defense against 2.qh8# but there is 1...ng8 same holds true for 1.qe5. Afterwards I looked at 1.Rf7+ Bxf7 2.qxf7+ kh8 3.qf6+ kg8 4.qe6+ but the king can escape via f8 and e8. So I dont see any combinations.

c) 1...qxc2 if white takes on c2 2...Nb3#

d) I don't have the slightest idea and would probably play something like Be3 or even O-O-O.

e) 1.Rxc4 with variations:

1...qxb5 2.dxe6 qxc4 3.qd7+ kf8 4.qf7#

2...rd8 3.rd4

1...bxd5 2.qxd5 c6 3.qxd7+ kxd7

2...qxd5 3.nxc7+ k.. 4.nxd5

f) when looking at this one, I think 1.Rxc4 in e) was probably false...

but now i think 1.rxc4 can be played and for the same reason as before the rook is untouchable (mate on f7)

g) 1.qd7+ qxd7 2.exd7+ Kxd7 3.rxe4 nf6 4.r4xc4 looks nice

kind regards,

svensp,

Thanks for the feedback!

If you play over the games in your browser at the link in the article you'll see what was played and/or Fritz's comments.

On b) I can force a repeat of moves Qf6, Ng8, Qe6, Ne7, ... I was a piece down to an eight-year old rated about 500 points below me and was happy to find the draw. But Fritz pointed out that by playing to activate my Bishop I could have played for a win. Sigh.

g) Your continuation works, but as played in the game I was able to take both pawns with check and sustain the initiative and not give him time to develop either rook.
 
b) Bg4 with threat of Qe5 am i right ?
