<<<FUNDAMENTAL THEOREM OF THREATS>>>

The number of times that a square is attacked (NA) and defended (ND) *cannot* be calculated by simply counting the number of pieces controlling that square. Rather,

<<THE NUMBER OF TIMES A SQUARE IS ATTACKED AND DEFENDED CAN BE COMPUTED ONLY AFTER -ALL- THE THREATS THAT CURRENTLY EXIST IN THE POSITIONAND THEIR -SEVERITY- (--) , AE WELL AS ALL THE THREATS THAT -CAN- -BE- -MADE- AND THEIR SEVERITY (++), HAVE BEEN TAKEN INTO ACCOUNT.>>

See 11 d4-d5! in I Kurnosov vs M Dzhumaev, 2008 for a *perfect* example of using <MAKING THREATS (++)> and <MEETING THREATS (--)> to count properly the number of times that the d5-square is attacked and defended. The d5-square is not 1 attacker (White d4-pawn), 2 defenders (Black b6-knight, e6-pawn); rather it is 2 attackers (White d4-pawn, c3-queen <CHECKING> on c6)(++), 1 defender (Black b6-knight, e6-pawn is <PINNED> to e8)(--)!!!!

In particular, you must account for the <<MOST OBVIOUS THREAT ON THE CHESSBOARD>>: <<<<THE THREAT TO CAPTURE A SQUARE>>>>, with or without an enemy piece or pawn on that square. The threat of an enemy unit to occupy a significant square must be dealt with.

And you must account for the <<FOUR TYPES OF SUBTLE THREATS>>:

Q: creates loose squares near enemy king
BRQQRB: attack every single square on their lines
N: defender cannot defend tactical base, target
P: threatens to advance to the blockading square

Game Collection: FOUR TYPES OF SUBTLE THREATS TO SQUARES

<Part I (++).> Being able to -MAKE- a threat (especially <CHECK> or a <MATE THREAT>, a <<SENTE>> move) means that you control a square -MORE- times than meets the eye (<THREATS GAIN TEMPO>).

<Part II (--).> Having to -MEET- a threat means that you control a square -FEWER- times than meets the eye (<OBLIGATION RESTRICTS MOBILITY>).

Maybe I can add attackers to the square with tempo, making a threat.

Maybe you can add defenders to the square with tempo, making a threat.

Maybe some of my attackers are tied down meeting threats.

Maybe some of your defenders are tied down meeting threats.

* The Book of Exodus.

The Egyptians wrote absolutely everything down, and as a result we know pretty much everything about ancient Egypt from its conception up until the burning of Alexandria. There is no record of a mass slavery of Hebrews to be found anywhere in all of Egyptology. The Israeli Archeological Survey did an intensive search over the Sinai peninsula trying to find evidence of a wandering hoard of Jews moving through a 300 mile stretch of desert from captivity to the promised land. If they had wandered through that area for 40 years, they would have left TONS of evidence: Pottery, droppings, footprints, encampments, cloth, animal tracks, etc. etc. They found nothing. All evidence suggests that the entire book of Exodus, including the character Moses, is a complete and utter fabrication, which seems to me to negate everything which came after it.

Need anything else?

  notyetagm: This pattern continued for a long time, even into an ending where Kramnik's extra exchange was well matched by Ponomariov's bishop pair and connected queenside passers. <<<Neither man handled the situation perfectly, and at one moment Ponomariov missed a shot that would have given him an advantage.>>>

  notyetagm: [32...Bc2!! and now Kramnik would be in trouble! The justification is obvious (the trick is considering a move like 33...Bc2 in the first place), but what White should do isn't. 33.Nxc3 Rxc3 34.Rb6 Rc4 35.Rb8+! Kh7 36.Rb5 a4 37.Rxh5+ Kg6 38.Rb5 b3 39.Ra1! Be4 Maybe White can hold the position, but all the chances are Black's.]

Moreover, the annotations take the form of textual instruction rather than twenty-ply side variations. The entertaining, informative game notes make this book an excellent instruction manual for players rated less than 1800. Take a look at some of the subtitles:

* The never-ending attack on h7
* A slow burning attack beats a temporary initiative * A wing pawn adds vital energy to an attack
* Why Alekhine beat Capablanca

Yes, but I always forget to go back there.

<Richard Taylor: What games (pref. modern or recent do you suggest to give ideas as to how counter the Trompowksi?>

Book on "Dealing with d4 Deviations" by Cox is supposed to be pretty good.

Also I *really* like Dembo's "Beating The Anti-King's Indians" for lines like the Tromp.

  Richard Taylor: I actually meant to try to communicate with <HeMateMe> but re the Trompowski I have played against it and I have also played the 1 d4 d5 2 Bg5 line ...the Torre or the Velmirovic.

I saw you had some good wins shown v the Tromp. but no examples of wins by Black.

Is the Cox book good for Black and White? Some books such as Gary Lanes c4 Sicilian book only give wins for White which is ridiculous. Well, o.k. to inspire White, but not so good if one just wants a general insight perhaps from both sides - I am invariably Black v that in any case...but I might try it one day and that apples to the Trompowski.

So Dembo's book is great also ..hmm.. I also want to get the anti Sicilian book - that is for anti anti Sicilians and for anti Sicilians!!

I am known here as very dangerous attacking player (who wins some wild games but crashes in the games in between! So I am working on that...) so even players near Master strength avoid my Najdorf but there is no way I can know all the variations of the Najdorf!! But they don't know what I do or don't know!! (Nor do I! There is so much theory!!) Or they just avoid playing the kind of game I prefer... (Well so far I am covered!)..and most of my opponents don't know anything...now the most dangerous can be those young players who either know nothing (but love tactics etc) about the opening as such or have studied a particular line (or lines) etc very well. So I will just play hoping my 'reputation' (greatly inflated) helps me not get bombarded!!

But I can also switch to "quiet" lines...so called.

  notyetagm: <POST PGN>
A very instructive game by Suri Vaibhav is his Round 3 win over Richard Wang from the 2009 WYCC, under 12.

Instead of attacking the Black h5-pawn with a piece sacrifice, he <COORDINATED> his pieces on the Black g6-pawn with 24 Qf3-e4, 25 Be2-d3 since he had the additional support of the White f5-pawn in this endeavor. Thus it was White f5-pawn, e4-queen, d3-bishop attackers of the Black g6-pawn versus Black f7-pawn defender. The g6-square hence collapsed and Black resigned on move 29.

  jessicafischerqueen: Hey thanks so much for keeping me up to date with your great analysis these past few weeks.

I've been so sick that I don't understand anything about chess.

But you see- because your analysis is so precise, and because you always use 800 FENS, I can actually learn from your posts no matter how sick I am.

I think you should consider publishing a Chess Tactics Book for Everyman Chess.

Why not? Look at all the material you have already compiled for such a project.

Seriously, I think you should look in to this.

Have to be more than USCF 1867 rated to get a book published. :-)

No one wants to buy a chess book written by a fish.
