Where do...This is the point I'm trying to make. Where do the visible salient cues originate? They start out as hidden salient cues that you do not see. A thinking process makes them visible. When you repeat a set of problems 30 times, most intricacies become visible. They are no longer hidden, and there is no longer a need to think about them. In fact they transferred from system 2 to system 1, from knowledge to skill and from hidden to visual.<br /><br />All this happens ideally in the study room. In the study room you can use side wheels like mnemonics, repetition, Stockfish and all sorts of help like consulting your fellow commenters. Behind the board these auxiliary tools are not allowed nor practical. You have no time for that.<br /><br />Behind the board you just see what is going on. The only thing you use system 2 for is stitching together what you see.

The purpose behind emphasizing extending the auras of pieces to the edge of the board is (again) a <b>reminder</b> to "<b>SEE</b>" through obstacles along a line of attack (which the formal rules of chess constrain—a piece CANNOT move through its own pieces, and can only go as far as the first opponent’s piece encountered along a line), not to apply that advice literally in all circumstances. In short, “it depends” is an accurate assessment of all such advice.<br /><br />My initial observations on the <b>lines</b> of attack was intentionally limited to <b>lines</b>. [As my wife is fond of pointing out, I am definitely “left-brained,” to the nth degree.] I was aware of the potential Knight forks and the subsequent operations but was trying <b>not</b> to address anything other than <b>lines</b> of attack, such as variations or even the knight moves. <b>This is not an <i>ex post facto</i> excuse</b> for me not grasping the intent behind the question: “<b><i>Can you describe the LoA landscape?</i></b>”. I have been hesitant to confess this, since it may seem as if I am trying to justify my “blindness” by claiming I saw everything initially.<br /><br />All of the various thinking techniques are part of the collection of “mini-skills” needed to create overall chess skill. Again, the metaphor of the bricks (mini-skills) and the wall (overall skill) is useful as an analogy.<br /><br />As for reaching an overall evaluation, I still consider Botvinnik’s simile of “escape from the swamp” to be apropos.<br /><br />Thinking will always be required to deal with the uniqueness of any position. No matter how much we absorb as patterns, we still have to fit it all together in a concrete solution.

The reason for this post is that with an invasion Stockfish often says, "you are winning", while I don't quite see the continuation. And often even lack the feel that it is winning. It is not necessary to see a mate in 35, but at least the gut feeling "this is winning" would already be nice.Temposchluckerhttps://www.blogger.com/profile/07977208394417444785noreply@blogger.comtag:blogger.com,1999:blog-10713928.post-13226182459863140392024-04-23T09:48:25.275+02:002024-04-23T09:48:25.275+02:00OTOH, if I write a post which is essentially about...OTOH, if I write a post which is essentially about line of attack and I forget to look at 50% of them, I take it that I have an issue that needs to be worked on.Temposchluckerhttps://www.blogger.com/profile/07977208394417444785noreply@blogger.comtag:blogger.com,1999:blog-10713928.post-82813270900576195962024-04-23T02:18:46.246+02:002024-04-23T02:18:46.246+02:00Think of all the varied mates with Knight(s).

A grande finale in the theater of the absurd: I for one find it ridiculous to imagine that I will ever <b>SEE</b> a checkmate taking 34 moves, no matter how forcing the individual moves might be! GM Aagaard’s observation is apropos: <b>And the rest is just a lack of technique…</b><br /><br />This reminds me of the engineer (with a measured IQ of 185 and two Masters degrees) who worried about a "hole" in his equations of motion for a 688-class submarine simulator - when it reached the speed of sound <b>UNDERWATER</b>, his equations failed. I did my best to assure him that the "hole" in his equations would NOT be a problem. <br /><br /><b>I’m done.</b><br /><br />D55 <b>-9.86 1...Re1</b> 2.Rxe1 Rf8 3.h4 Ne6 4.Qe3 Ng7 5.Qe7 b6 6.Kh2 d4 7.Qxf6 Rxf6 8.Re7 Rg6 9.Nf7+ Kg8 10.Nh6+ Kf8 11.Rf7+ Ke8 12.Rxg6 hxg6 13.Rxg7 c5 14.Rxg6 c4 15.Kh3 d3 16.cxd3 c3 17.Rc6 Ke7 18.Rxc3 Ke6 19.Rc4 a5 20.Ng4 b5 21.Rc1 Kd7 22.bxa5 Kd6 23.a6 Ke6 24.a7 Kd6 25.a8=Q Ke7 26.Qa7+ Kd8<br /><br />D55 <b>Mate -34 1...Qxd6</b> 2.Qd4+ Kg8 3.Rxg5+ Qg6 4.Qf6 Rf8 5.Rxg6+ hxg6 6.Qxg6+ Kh8 7.Rxf8+ Rxf8 8.h4 d4 9.Kh2 b6 10.Qxc6 Kg7 11.Qd7+ Kh6 12.Qxd4 Rg8 13.Qxb6+ Rg6 14.Qa7 Rg4 15.Qe7 Rg6 16.Qf7 Rg7 17.Qf6+ Kh7 18.Qxa6 Rf7 19.Qc4 Kg6 20.b5 Rf5 21.b6 Rf7 22.Qxf7+ Kxf7 23.b7 Ke6 24.h5 Kd6 25.b8=Q+ Kc5 26.Qb7 Kd4 27.h6 Ke5 28.h7 Kd4 29.Qb4+ Ke3 30.Qc3+ Ke4 31.Qc4+ Ke3<br /><br />D55 <b>Mate -22 1...Nf3</b> 2.Nxe8 Rxe8 3.Rgxf3 Qe5 4.Rf7 Qe4 5.Qg3 Qg6 6.Qc7 h6 7.Rf8+ Rxf8 8.Rxf8+ Qg8 9.Qf7 Qxf8 10.Qxf8+ Kh7 11.h4 d4 12.Qf7+ Kh8 13.Kh2 d3 14.cxd3 h5 15.Qxh5+ Kg8 16.Qg5+ Kf7 17.h5 a5 18.h6 a4 19.Qf5+ Ke7 20.h7 Kd6 21.h8=Q Kc7 22.Qfe5+ Kd7 23.Qhe8#<br /><br />D55 <b>Mate -15 1...Re3</b> 2.Rxf6 Rxd3 3.cxd3 Kg7 4.Re6 h6 5.h4 Rf8 6.hxg5 h5 7.g6 c5 8.Ne8+ Rxe8 9.Rxe8 cxb4 10.Re7+ Kf6 11.g7 Kxe7 12.Rg6 Kd7 13.g8=Q Kc7 14.Qxd5 bxa3 15.Qd6+ Kc8 16.Rg8#<br /><br />D55 <b>Mate -13 1...Qxf1+</b> 2.Qxf1 Re6 3.Qa1+ d4 4.Qxd4+ Kg8 5.Rxg5+ Rg6 6.Qe5 Rf8 7.Nf5 Rxf5 8.Rxf5 h6 9.Qe7 Rg7 10.Rf8+ Kh7 11.Qe4+ Rg6 12.Rf7+ Kh8 13.Qe5+ Kg8 14.Qe8#<br /><br />D55 <b>Mate -11 1...Qg6</b> 2.Rxg5 Rf8 3.Rxg6 Rxf1+ 4.Qxf1 hxg6 5.Qf6+ Kh7 6.h4 Rg8 7.Nf7 Re8 8.Kh2 d4 9.h5 gxh5 10.Ng5+ Kg8 11.Qg6+ Kf8 12.Qf7#<br /><br />D55 <b>Mate -11 1...Qe5</b> 2.Rxg5 Qxd6 3.Qd4+ Re5 4.Rxe5 Kg8 5.Rg5+ Qg6 6.Rxg6+ hxg6 7.Qf6 Re8 8.Qxg6+ Kh8 9.Qxe8+ Kg7 10.Qf7+ Kh6 11.Rf5 b5 12.Rh5#<br /><br />D55 <b>Mate -11 1...Qg7</b> 2.Rxg5 Qxg5 3.Nf7+ Kg8 4.Nxg5 Re7 5.Qf5 h6 6.Qg6+ Rg7 7.Qe6+ Kh8 8.Rf6 hxg5 9.Rh6+ Rh7 10.Qf6+ Kg8 11.Rg6+ Rg7 12.Qxg7#<br /><br />D55 <b>Mate -9 1...Qe7</b> 2.Qd4+ Kg8 3.Nf5 Kf7 4.Nxe7+ Ke6 5.Nxd5 Kd7 6.Qg7+ Nf7 7.Rxf7+ Kd6 8.Rd7+ Ke6 9.Re3+ Kf5 10.g4#<br /><br />D55 <b>Mate -9 1...Rf8</b> 2.Rxf6 Rxf6 3.Qd4 Rf8 4.Rxg5 c5 5.Qe5 h6 6.Rg6 Kh7 7.Rxf6 Rxf6 8.Qxf6 cxb4 9.Ne8 bxa3 10.Qg7#<br /><br />D55 <b>Mate -9 1...Re6</b> 2.Rxf6 Rxf6 3.Qd4 Rf8 4.Rxg5 c5 5.Qe5 h6 6.Rg6 Kh7 7.Rxf6 Rxf6 8.Qxf6 cxb4 9.Ne8 bxa3 10.Qg7#<br /><br />D55 <b>Mate -9 1...h6</b> 2.Rxf6 Re1+ 3.Rf1 Rxf1+ 4.Qxf1 Rg8 5.Nf7+ Kh7 6.Qf5+ Kg7 7.Nxg5 hxg5 8.Rxg5+ Kh6 9.Rxg8 a5 10.Qg6#<br /><br />D55 <b>Mate -9 1...Rad8</b> 2.Rxf6 Rxd6 3.Qd4 Re1+ 4.Rf1+ Kg8 5.Rxg5+ Rg6 6.Rxg6+ hxg6 7.Rxe1 Kf7 8.Qf4+ Kg8 9.Re7 d4 10.Qb8#<br /><br />D55 <b>Mate -8 1...Qf4</b> 2.Rxf4 h6 3.Rf1 Re4 4.Nxe4 dxe4 5.Qd6 Kg7 6.Qe7+ Kg8 7.Rf6 Kh8 8.Rxh6+ Kg8 9.Rxg5#<br /><br />D55 <b>Mate -8 1...Qb2</b> 2.Nxe8 Rxe8 3.Rxg5 h6 4.Rg6 Re4 5.Qg3 Qf6 6.Rgxf6 Rg4 7.Qxg4 Kh7 8.Qg6+ Kh8 9.Rf8#Robert Coblehttps://www.blogger.com/profile/12427520849707914818noreply@blogger.comtag:blogger.com,1999:blog-10713928.post-318183162337950372024-04-22T13:36:42.229+02:002024-04-22T13:36:42.229+02:00Thanks Robert.

(I have no idea what engine was used to create the solution.)<br /><br /><b>0...Kh8 1.Nd6</b><br />+ +5.83 1. Nd6 <br />+ TRY AGAIN +2.52 1. Rxg5<br />+ TRY AGAIN +2.12 1. Ne3<br />+ +0.41 1. Kg1<br />+ +0.22 1. Nd4<br /><br /><b>1...Re1</b><br />+ -5.78 1... Re1<br />+ -7.48 1... Qxd6<br />+ -7.76 1... Nf3<br />+ -9.30 1... Re3<br />+ -13.25 1... Qg6<br /><br /><b>2.Rxe1</b><br />+ +6.27 2. Rxe1<br />+ TRY AGAIN +2.13 2. Nf7+<br />+ -0.54 2. Rg1<br />+ -2.93 2. Nf5<br />+ -3.26 2. Kg1<br /><br />Obviously, the breadth of the analysis was set at 5 alternatives. There is a significant difference between the “best” move [<b>1. Nd6</b>] and the next two alternatives [<b>1. Rxg5</b> and <b>1. Ne3</b>]. The final two alternatives [<b>1. Kg1</b> and <b>1. Nd4</b>] would not make my cutoff for candidate moves. Not because of the poor relative score (which I did not see until after determining the first two moves, playing what I considered to be the better move [<b>1. Nd6</b>] and learning that I had chosen the “correct” solution), but because they don’t seem to meet the requirements of the position. White has significant tactical shots and superior assets in the vicinity of the Black King. Recall GM Aagaard’s 2nd principle regarding <b>Momentum</b>: “<i>Once you have improved your position to the maximum, <b>YOU MUST EXECUTE YOUR ATTACK WITH THE GREATEST POSSIBLE PACE.</b></i>”<br /><br />My uninformed question is simple:<br /><br /><b>Why would any moves beyond those first three alternatives be considered as candidate moves?</b><br /><br />It seems difficult (to ME) to justify investigating alternatives beyond what can be rationally <b>SEE</b>n as the strongest alternatives from a human perspective. If the overall objective is improving skill over-the-board, I fail to <b>SEE</b> how exploring arbitrary inferior alternatives improves skill.<br /><br />It is the same problem I have with super-accurate valuations based on the scale of values (hundredths of a point) proposed by GM Larry Kaufman. Centi-pawn evaluations are fine for computer analysis but, absent knowing and understanding all of the scoring functions involved, are worse than useless for humans. We can’t calculate to that level of distinction even if we tried. Even the Reinfeld relative valuations based on a pawn being equal to 1 are problematic: are 9 pawns equal in value to a Queen? How could they be, given that having 9 pawns on the board is <b>ILLEGAL</b>?!?<br />Robert Coblehttps://www.blogger.com/profile/12427520849707914818noreply@blogger.comtag:blogger.com,1999:blog-10713928.post-76440478322951255462024-04-21T19:55:27.585+02:002024-04-21T19:55:27.585+02:00Of course from attacking Manual not art of attack....Of course from attacking Manual not art of attack....Takchessnoreply@blogger.comtag:blogger.com,1999:blog-10713928.post-46504884988023494362024-04-21T19:30:34.552+02:002024-04-21T19:30:34.552+02:00You might find this game interesting as to the eve...You might find this game interesting as to the ever changing invasion squares and mating attacks.

With a check it is forced to return. I struggled as to why this is so . I now think it because if it was intially there it would use it's tempo to take the attacker. By having moved from the square it has to use its tempo to return ....Something that I had a blind spot. <br /><br />Here are some other things I calculated an initial pin by 1.

Both are castled Kingside . Black has a Queenside majority of pawns 4 vs 3 pawns.<br /><br />Strength vs Weakness.<br />Black Rooks support each other but arent active. Unlikely to be an 8th row mate for white. Neither side have forward pawns that are likely in the short term to promote . Queen is loose for Black. Knight is protected by Queen which can lead to entrapment.<br />H7 is aligned with the Queen but Unlikely to get enoght tempos to get white rooks into action. At present there is a discover attack on the queen with any knight move and that the rook and capture blacks Knight. A discovered attack by Ne6 (rook attacking Queen and kNight attacking rook seems possible due to queen entrapment on the long diagonal Note N & K present position and suspectible to a Knoight fork from f7 . Also the classic mate of Knight f7 and rook on g file would be mate. Also looked at kicking the N with an h pawn. white has some back rank issues give the queen some duties that may be relinquished with some tempo In one line the checking queen cant be capture due to whites N blocking the black queens rays is she caputured the rook. <br /><br /><br />Blacks King is not well protected thoughts are 7th file mate on H7 with a future h file rook or perhaps arabian knight mate supporting the mate. The a1 H8 diagonal is extremely weak and if the queen is lured off the diagonal she can be entrapped even on the g7 square (whites queen supported by Knight in present position. This duty makes the knight and other squares free for white.<br /><br />That's what I got will let you know if I forgot any thoughts in this post. <br /><br />JImtakchessnoreply@blogger.comtag:blogger.com,1999:blog-10713928.post-65674273091789215822024-04-21T09:32:24.218+02:002024-04-21T09:32:24.218+02:00Update part 2 in greenUpdate part 2 in greenTemposchluckerhttps://www.blogger.com/profile/07977208394417444785noreply@blogger.comtag:blogger.com,1999:blog-10713928.post-23434218070839540362024-04-21T03:20:00.203+02:002024-04-21T03:20:00.203+02:00Update part 1 in blueUpdate part 1 in blueTemposchluckerhttps://www.blogger.com/profile/07977208394417444785noreply@blogger.comtag:blogger.com,1999:blog-10713928.post-80975089053237515792024-04-21T02:57:50.778+02:002024-04-21T02:57:50.778+02:00Spent a few hours while on a commercial.

For the past few years, I have switched to studying more dynamics than statics. It is my opinion that the current style of play is very dynamic, and thus there is considerably more emphasis on tactical issues in all stages of the game. Perhaps there are now sufficient resources to formulate a more generalized approach to all aspects of the middle game.<br /><br />Takchess wrote an excellent review of GM Aagaard’s <b><i>Attacking Manual Volume 1</i></b> on <b>Goodreads</b>:<br /><br /><b>Link: https://www.goodreads.com/book/show/2717054-attacking-manual-volume-1</b><br /><br />GM Aagaard, in his later book <b><i>Grandmaster Preparation: Thinking INSIDE The Box</i></b> [which summarizes the <b><i>Grandmaster Preparation</i></b> series of workbooks], added an eighth broad principle of dynamic strategy to those previously detailed in <b><i>Attacking Manual Volume 1</i></b>.<br /><br />The eight broad <b>dynamic</b> strategical principles [emphasis added] are:<br /><br /><b>1: Include ALL the pieces in the attack.</b><br />“Local superiority is what it is all about.”<br />“Include the last piece. Include as many pieces in the attack as you can <b>WITHOUT LOSING YOUR MOMENTUM</b>.”<br /><br /><b>2: Momentum</b><br />“Steinitz: <i>When a sufficient advantage has been obtained, a player <b>MUST ATTACK</b> or the advantage will be dissipated.</i>”<br />“Once you have improved your position to the maximum, YOU MUST EXECUTE YOUR ATTACK WITH THE GREATEST POSSIBLE PACE.”<br />“A lead in development should be exploited at its zenith.” <br /><br /><b>3: Colour</b><br />“Most chess pieces are colour blind!”<br />“Controlling one colour of squares is one of the main indications [“<b>CLUE!</b>”] of a promising attack.”<br /><br /><b>4: Quantity beats Quality</b><br />“A piece can only attack a square <b>ONCE</b>, no matter its alleged exchange value in pawns.” [Corollary: A piece/pawn occupying a square <b>CANNOT</b> attack/control that square. Think about the Classical idea of “occupying center squares with pawns.”]<br /><br /><b>5: Attack the WEAKEST square.</b><br />“You should strike at the weakest spot in the opponent’s position.”<br /><br /><b>6: Attack the STRONGEST square.</b><br />“Strike at a square that the opponent has overprotected, in order to ruin his coordination and get through to the real weakness.”<br /><br /><b>7: Evolution/Revolution</b><br />“Get a good feeling for the attacking flow: prepare the forces as much as you can, do with them what you can, and then the position will change, usually in a big way.”<br />“Regroup before proving compensation.”<br /><br /><b>8: The Killzone</b><br />“<i><b>A mating attack is likely to happen in a limited area of the board.</b> If the opponent’s king manages to escape this area, the attack is likely to fail.</i>”Robert Coblehttps://www.blogger.com/profile/12427520849707914818noreply@blogger.comtag:blogger.com,1999:blog-10713928.post-76577251621204552912024-04-21T00:56:54.936+02:002024-04-21T00:56:54.936+02:00And one line of attack for black.And one line of attack for black.Temposchluckerhttps://www.blogger.com/profile/07977208394417444785noreply@blogger.comtag:blogger.com,1999:blog-10713928.post-41624957461721311322024-04-21T00:50:55.591+02:002024-04-21T00:50:55.591+02:00I hope to find time tomorrow to work out more deta...I hope to find time tomorrow to work out more details and add it to the post.
