Mo\u017enosti jezdce<\/strong>

Jezdec p\u0159in\u00e1\u0161\u00ed na \u0161achovnici chaos<\/strong>, komplikace, p\u0159ekvapen\u00ed. Objevuje se na ne\u010dekan\u00fdch m\u00edstech. Velmi r\u00e1d d\u00e1v\u00e1 vidle<\/strong>.

Vypl\u00fdv\u00e1 to z jeho klikat\u00e9ho chodu<\/strong>.

\"\"<\/a>
U takov\u00e9ho st\u0159elce b\u00fdv\u00e1 na prvn\u00ed pohled vid\u011bt, kam m\u00ed\u0159\u00ed.

\"\"<\/a>
Naopak u kon\u011b m\u016f\u017ee vypadat cesta jako pr\u016fchod bludi\u0161t\u011bm – a to jsem nakresli jen jednu mo\u017enost, je tam spousta dal\u0161\u00edch.

\"\"<\/a>
U\u017e jsme si, mysl\u00edm, ukazovali, \u017ee jezdec uprost\u0159ed desky m\u016f\u017ee na osm pol\u00ed. Ale to plat\u00ed jen v jeho prvn\u00edm tahu!

\"\"<\/a>
Pole, kam m\u016f\u017ee ve druh\u00e9m tahu, jsem zn\u00e1zornil \u017elut\u011b. Vid\u00edte, \u017ee je to 27 pol\u00ed skoro po cel\u00e9 \u0161achovnici!

Krom\u011b jin\u00e9ho si v\u0161imn\u011bte, \u017ee v prvn\u00edm tahu m\u016f\u017ee z \u010dern\u00e9ho jen na b\u00edl\u00e1 pole, ve druh\u00e9m z b\u00edl\u00fdch jen na \u010dern\u00e1. Jezdec to pravideln\u011b st\u0159\u00edd\u00e1: \u010dern\u00e9 – b\u00edl\u00e9 – \u010dern\u00e9 – b\u00edl\u00e9 …<\/strong>

To v\u0161echno t\u0159eba znamen\u00e1, \u017ee kdy\u017e bude \u010dern\u00fd kr\u00e1l na \u010dern\u00e9m poli, skoro v\u0161ude m\u016f\u017ee dostat od jezdce d4 jedn\u00edm tahem \u0161ach!

To by je\u0161t\u011b nebylo tak \u00fa\u017easn\u00e9, d\u00e1ma a v\u011b\u017e se na pr\u00e1zdn\u00e9 \u0161achovnici dostanou druh\u00fdm tahem \u00fapln\u011b kamkoliv, proto jsou taky siln\u011bj\u0161\u00ed ne\u017e jezdec. Ale jezdec se tam narozd\u00edl od nich dostane i p\u0159es p\u0159ek\u00e1\u017eky, je to jedin\u00e1 figura, kter\u00e1 um\u00ed p\u0159eskakovat!

\"\"<\/a>

<\/strong>Takov\u00e1hle p\u011b\u0161cov\u00e1 ohr\u00e1dka pro jezdce nic neznamen\u00e1. Jako by um\u011bl proch\u00e1zet zd\u00ed.

\"\"
<\/a>Pro v\u0161echny ostatn\u00ed figury, dokonce i pro d\u00e1mu, by to bylo v\u011bzen\u00ed.

Z toho vypl\u00fdv\u00e1, \u017ee jezdec je siln\u00fd v zav\u0159en\u00fdch pozic\u00edch<\/strong>, to jsou takov\u00e9, kde se figurky, hlavn\u011b p\u011b\u0161ci, dlouhodob\u011b pletou a jen tak se nehnou.

\"\"<\/a>
<\/a>T\u0159eba tohle je zav\u0159en\u00e1 pozice. Oba jezdci jsou tam velmi siln\u00ed, \u0161ipkami jsem uk\u00e1zal siln\u00e1 pole, na kter\u00e1 m\u016f\u017eou. Kdyby m\u00edsto nich st\u00e1li st\u0159elci, v\u011b\u017ee nebo d\u00e1my, mo\u017enost\u00ed by m\u011bli mnohem m\u00e9n\u011b.

\"\"
<\/a>Jezdci pot\u0159ebuj\u00ed op\u011brn\u00e1 pole v centru<\/strong>. To jsou pole, na kter\u00fdch jsou kryti a hlavn\u011b na kter\u00fdch nemohou b\u00fdt napadeni p\u011b\u0161cem. B\u00edl\u00fd tu z\u00edskal kr\u00e1sn\u00e9 op\u011brn\u00e9 pole d5 (pokro\u010dilej\u0161\u00ed jist\u011b rozezn\u00e1vaj\u00ed Sv\u011b\u0161nikovovu variantu sicilsk\u00e9, kter\u00e1 je na tomto jezdci za b\u00edl\u00e9ho zalo\u017eena).\u00a0<\/em>Naopak \u010dern\u00fd op\u011brn\u00e9 pole d4 zat\u00edm nem\u00e1, b\u00edl\u00fd ho m\u016f\u017ee napadnout tahem c3.

\"\"
<\/a>N\u011bkdy m\u016f\u017ee b\u00fdt i jezdec p\u011b\u0161ci omezen. Tohle je zase zav\u0159en\u00e1 pozice (ze zav\u0159en\u00e9 \u0161pan\u011blsk\u00e9), kter\u00e1 by m\u011bla jezdc\u016fm vyhovovat v\u00edc ne\u017e t\u0159eba st\u0159elc\u016fm, ale Jb7 tu stoj\u00ed dlouhodob\u011b \u0161patn\u011b – omezuj\u00ed ho b\u00edl\u00ed i \u010dern\u00ed p\u011b\u0161ci. Nem\u016f\u017ee a nebude moci na a5, na c5, ani na d6. M\u016f\u017ee na d8, ale zase pak nebude moci ani na c6, ani na e6. Mohl by si uvolnit pole f7, ale to n\u011bjakou dobu potrv\u00e1 a b\u00edl\u00fd mezit\u00edm bude n\u011bco hr\u00e1t.

\"\"<\/a>
Dal\u0161\u00ed d\u016fle\u017eit\u00e1 v\u011bc je, \u017ee jezdec m\u00e1 mnohem v\u00edc mo\u017enost\u00ed uprost\u0159ed \u0161achovnice ne\u017e na kraji.<\/strong> Jak vid\u00edte, v rohu m\u016f\u017ee jen na dv\u011b pole, na kraji na \u010dty\u0159i, uprost\u0159ed na osm (\u00fakol: najd\u011bte, odkud m\u016f\u017ee na t\u0159i nebo na \u0161est pol\u00ed). Proto se v\u011bt\u0161inou sna\u017e\u00edme jezdce centralizovat. Tarrasch, kter\u00e9ho jsem prob\u00edral s pokro\u010dil\u00fdmi, je autorem slavn\u00e9ho v\u00fdroku: „Ein\u00a0Springer am Rande bringt Kummer und Schande,“\u00a0<\/em>tedy „jezdec na kraji p\u0159in\u00e1\u0161\u00ed sou\u017een\u00ed a hanbu“, voln\u011b p\u0159elo\u017eeno „je jen pro ostudu“.

A je\u0161t\u011b rada do koncovky:

\"\"<\/a>
Pole, kter\u00e1 jsou od jezdce \u0161ikmo o jedno, jsou pole, kam se dostane za dva tahy<\/strong> – tedy u\u017e v p\u0159\u00ed\u0161t\u00edm tahu m\u016f\u017ee d\u00e1t \u0161ach kr\u00e1li, kter\u00fd tam stoj\u00ed.

\"\"<\/a>
Stejn\u00e9 – zase na dva tahy<\/strong> – je to u pol\u00ed, kter\u00e1 jsou vodorovn\u011b nebo svisle vzd\u00e1lena o dv\u011b, i tam se jezdec snadno dostane.

\"\"<\/a>
Slo\u017eit\u011bj\u0161\u00ed je to u pol\u00ed, kter\u00e1 jsou vodorovn\u011b nebo svisle t\u011bsn\u011b vedle kon\u011b – tam m\u016f\u017ee a\u017e t\u0159et\u00edm tahem<\/strong> (tedy \u0161ach druh\u00fdm).

\"\"<\/a>
A nejbezpe\u010dn\u011bj\u0161\u00ed jsou pole vzd\u00e1len\u00e1 \u0161ikmo o dv\u011b – na n\u011b se dostane a\u017e \u010dtvrt\u00fdm tahem<\/strong> (tedy \u0161ach d\u00e1 t\u0159et\u00edm).

\"\"<\/a>
Tak\u017ee kdy\u017e v\u00e1m d\u00e1 jezdec \u0161ach jako zde, nebude v\u011bt\u0161inou dobr\u00e9 j\u00edt na e5 nebo na d6, tam v\u00e1m d\u00e1 \u0161ach hned znova. Spr\u00e1vn\u00e9 je j\u00edt na d5, tam se jezdec na kr\u00e1le nedostane a je p\u0159itom napaden, nebo, kdy\u017e chcete m\u00edt n\u011bjak\u00fd \u010das od \u0161ach\u016f pokoj, jd\u011bte na f6 a je klid. Kdy\u017e si takov\u00e9 \u00fastupy zafixujete, nestane se v\u00e1m, \u017ee byste si p\u0159i nedostatku \u010dasu nalezli do vidli\u010dky – to jsou z\u00e1kladn\u00ed \u0161achov\u00e9 n\u00e1vyky.<\/p>\n","protected":false},"excerpt":{"rendered":"
