Although the fight will also take place on both fronts here, which is welcomed by the side with the bishop, the blockade speaks in favour of the knight! <em>Match score<\/em> we can therefore call it a drawn 1-1.

Explanations are sometimes at least briefly indicated there, but I assume that these strategic methods are generally known, just as the concept of opposition is known to beginners.<\/p>\n<p>However, the situation is different with\u00a0<strong>tools<\/strong>, which we could call <strong>special<\/strong>! Before we start with the concrete study, let us first familiarise ourselves with these specific instruments or helpers. If the 3xMost rule generates three situations favouring the bishop or knight, then our <strong>two special aids each serve their master in a 1-1 ratio!<\/strong><\/p>\n<p><strong>For the knight speaks<\/strong> the so-called weakness of the complex of squares of the opposite colour to the opponent's bishop (which we can already clearly see in Studer's diagram above), <strong>for the bishop<\/strong> then a special term <strong>Sieve<\/strong>, which was patented by the exceptionally talented and successful grandmaster trainer Alexandr Nikolayevich Panchenko. I believe the diagrams below will clarify everything without any problems.<\/p>\n<p style=\"text-align: center;\"><a href=\"https:\/\/skolasachu.com\/wp-content\/uploads\/2024\/05\/Slabost-poli-a-Reseto.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-1974\" src=\"https:\/\/skolasachu.com\/wp-content\/uploads\/2024\/05\/Slabost-poli-a-Reseto-300x150.jpg\" alt=\"\" width=\"432\" height=\"216\" srcset=\"https:\/\/skolasachu.com\/wp-content\/uploads\/2024\/05\/Slabost-poli-a-Reseto-300x150.jpg 300w, https:\/\/skolasachu.com\/wp-content\/uploads\/2024\/05\/Slabost-poli-a-Reseto-1024x512.jpg 1024w, https:\/\/skolasachu.com\/wp-content\/uploads\/2024\/05\/Slabost-poli-a-Reseto-768x384.jpg 768w, https:\/\/skolasachu.com\/wp-content\/uploads\/2024\/05\/Slabost-poli-a-Reseto.jpg 1456w\" sizes=\"auto, (max-width: 432px) 100vw, 432px\" \/><\/a><\/p>\n<p>In the diagram on the left, the reader can easily identify the overwhelming advantage of the Knight. The poor Bishop in a blocked position helplessly <em>stares at the immobilised colony<\/em> of its own pawns in the centre and on the queenside. Thanks to this, the white king can literally walk like on a red carpet welcoming the most important state visitors all the way to the very rear of Black's position. True, if we start calculating variations, we find that the red carpet unfolds <em>only<\/em> on c5; behind it the welcoming committee in the form of the black king will already be lurking (this example will still be the subject of our study in the viewer). In Black's position, a phenomenon occurs which we can call <strong>a complex of weak squares<\/strong> in this case of the black colour. For easier memorisation and a simpler, shorter name, I borrowed terminology from medicine. The weakness of the complex of black squares is called by my pupils <strong>erythropenia<\/strong> (a deficiency of red blood cells, that red carpet).<\/p>\n<p style=\"text-align: center;\"><a href=\"https:\/\/skolasachu.com\/wp-content\/uploads\/2024\/05\/Erytropenie.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-1976\" src=\"https:\/\/skolasachu.com\/wp-content\/uploads\/2024\/05\/Erytropenie.jpg\" alt=\"\" width=\"212\" height=\"120\" \/><\/a><\/p>\n<p>The opposite phenomenon, i.e. weakness of the white squares, is then leukopenia (a lack of white blood cells indicates in our case directly an infection in the body of the position).<\/p>\n<p>The situation in the right diagram with the advantage of the bishop is conceptually more complicated. The Soviet, later Russian, grandmaster, excellent trainer, theoretician and didactician Alexandr Panchenko noticed a frequently recurring phenomenon in his analyses of positions with a bishop advantage. In my opinion, we cannot speak here of a weakness of the complex of squares, because it is hardly a permanent phenomenon like the red carpet, but the property of the knight, which was already pointed out by Capablanca, namely the (limited) ability to control squares of only alternating colours during its movement, leads for example to the situation shown in the diagram. White must move the knight (now or in a few moves) and Black will penetrate into the opponent's rear through <strong>the f3 square<\/strong>! This <strong>point of origin<\/strong> was called Panchenko <strong>Sieve<\/strong>! If we realise the advantage of a bishop over a knight, this phenomenon occurs very often, as the examples I <em>present to celebrate the bishop<\/em> show in the viewer.<\/p>\n<p style=\"text-align: center;\"><a href=\"https:\/\/skolasachu.com\/wp-content\/uploads\/2024\/05\/Pancenko.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-1978\" src=\"https:\/\/skolasachu.com\/wp-content\/uploads\/2024\/05\/Pancenko.jpg\" alt=\"\" width=\"153\" height=\"211\" \/><\/a><\/p>\n<p style=\"text-align: center;\"><em>Grandmaster Alexandr Nikolaevich Panchenko (1953-2009), a prominent coach and theoretician.<\/em><\/p>\n<h4><span style=\"color: #333399;\"><strong>The 3xMost rule in practice<\/strong><\/span><\/h4>\n<p>Let us now finally take a closer look at several endgames.

Mikhail Ivanovich launched his patented defence of the Queen\u2019s Gambit against the newly crowned world champion, exchanged both his bishops, and then a fierce battle between the pair of bishops and knights flared up.

Well, I started from scratch: I created a database, statistics, and within the possibilities of the time, I began to study White's setup. I could not avoid encountering the name of Vladimir Georgiev, a Bulgarian grandmaster who in 1997 and 1999 won at least two serious games with Black precisely thanks to the invisible move (just like Sergei Tivjakov).<\/p>\n<p>But what a surprise it was when I looked through the entire list of games.
