Some good tips in the above posts that I willl try to keep in mind.

I think I may be a bit thick, as I still cannot see how castling has anything to do with my knight at g4 staying alive. :doh: I have a hard time keeping all these variations straight, and sometimes I carry them way farther than anything I could reasonably calculate.

To make matters worse, I spent all that time calculating (often typo'd or imprecise)variations for .....
White9. h4xg5, and then Letum goes and moves Bc1xg5


Right now, I'm considering these moves;

Black 9. h7-h5. or Be7xg5 or f7-f5

Well, you reserve most of your time to calculate what you consider his strongest move, or what you expect him to move, but you also keep an eye on other options he has. It's about time management, and setting priorities.

Of the moves you mentioned, focus on f5, although there is another move that is somewhat recommending itself. h5 just cripples your casteling position and opens your king'S flank for nothing. White'S answer to your weak move g5 has not been as strong as possible, but with h5 and Bg5: you again hand over the advantage to White.

It seems to me that right now the greatest threat is white 10 f2-3
or white 10 Nc3xd5. Is that an incorrect assumption?

these are the variations I have worked out(trying to keep them shorter and error-free)

Black 9. f7-f5
10. white f2-f3, black f5-f4 white's queen is lost.

10. white e4xf5, black Nd4xf5 White's only recourse is Qg3-f3. It seems like this could be followed by black qd8xe7 should White choose to attack the bishop at e7. Should white's queen attack black's knight at g4, black responds with Nf5-e3+
and white loses his queen.

10. white Nc3xd5, black f5-f4. It seems like this could be followed by black qd8-d7 should white choose to attack the bishop at e7. I don't see any other moves that save his queen in the end.

As such, I submit f7-f5 for consideration.

I'm not sure if I see it. I think you might be recommending d5xe4. I haven't pursued that to a great extent yet. I don't have a lot of time to look at it now, but I think it might be good. Looking at it briefly, I think it may be better than f7-f5.


















f7-f5 seems like the best move to counter these threats.

Well, yes. Very complicated situation, i admit I struggle myself a bit now.

Indeed, de4: is what I meant. It opens the d-line on which the king is positioned, but unfortunately it moves your queen off that nice firing position on d8: Be7: would be White's reply most certainly.

In case of your move not being de4: but f5, you need to take into account four possible answers: White moves Nd5: or Be7: (probably white' two best answers), f4 (making things even more complicated to calculate), and ef5: also should not been ignored.

If you feel you suffer from overload, try to simplify the situation, if you see a possibility. Maybe you do not make the best moves that way, but it cannot be helped: you need to come along with the skills oyu have NOW, not in the future, so try to chnage situation that you can calculate it again. juzst make sure that your way to take complexity out of the situation is a safe way and does not leave you at your disadvanatge. remember that White faces the same calculation problems like you.

A bit chess psychology sometimes is on order. Namely: bluffing. But this i never have written, so treat it as if you never have read it.

welcome in the middle of the maelstrom. The match approaches the event horizon. Paddle for your life, or sink like a stone.:D

Despite the fact that English is your second language you certainly have a way with words:D

I need a bit more time to consider my move. In the meantime, more suggestions (edit-from anyone)would be appreciated.:up:

If there are no objections.....

white 9. bc1xg5
black 9. f7-f5, official move

no...I was right...Nc3xd5

baggygreen 09-15-08 06:14 PM

My timid guesses for the next couple...

Black QD8-D6 (less likely for White G5xE7 because theres not much to gain from that now white can't trap the queen in there - a 1 for 1 trade on bishops benefits neither)

White could castle

Black H7-H6 which would force the white bishop to retreat and as such start opening up the right hand side a bit.

maybe?

I see no reason why to make Black'S life more complicated than necessary by moving Qd6. It is a long - a very long combination before black gets back that figure he would immediately lose, and that would distract him from pushing his attack.

h6 lets Black lose a figure without compensation or later taking-back, i think.

Lance, you moved g5 and f5 and by that corrupted your king'S flank completely, short casteling now makes no more sense. the king's perspective thus lies in long casteling, if he still must do it. You started to let your batallions engage in frontal attack on the king's wing, well, now go all the way and push as far as you can.

there is only one good move, I would say. Black trails behind by two pawns currently, but his initiative currently seems to compensate for that. If he loses that initiative, then the loss will make itself being felt. I'm not sure that it will hold.

Letum 09-15-08 07:33 PM

I may be in the corner of the ring, but I'm throwing out the punches still. :D

Skybird 09-15-08 07:40 PM

Let's see if he can change that! ;)

.

Im a bit lost i think sky.. how does H6 make black lose a piece with no gain? the bishop can either take the pawn, and subsequently be taken by the rook, or he must retreat - and retreat quite a way, given the positions in the centre of the board...?

Im probably missing something very very obvious
