Klasisk\u0101 s\u0101kuma priek\u0161roc\u012bba<\/p>\n
P\u0113tnieki uzskata, ka klasisk\u0101 \u0161aha s\u0101kuma poz\u012bcija, kas tiek izmantota gadsimtiem ilgi, b\u016btu j\u0101p\u0101rskata, jo t\u0101 praktiski vienm\u0113r dod nelielu, bet stabilu priek\u0161roc\u012bbu baltajiem.<\/p>\n

Jauns p\u0113t\u012bjums par simetriju<\/p>\n
Tom\u0113r jauns p\u0113t\u012bjums liecina, ka pat \u0161is variants nav pietiekami l\u012bdzsvarots. Statistikas teor\u0113ti\u0137is Marks Bartel\u0113mi no Par\u012bzes-Sakl\u0113 universit\u0101tes analiz\u0113jis visas 960 Chess960 s\u0101kuma poz\u012bcijas, izmantojot \u0161aha dzin\u0113ju Stockfish. Vi\u0146\u0161 nov\u0113rt\u0113jis l\u0113mumu sare\u017e\u0123\u012bt\u012bbu un p\u0101rbaud\u012bjis, vai pirm\u0101 g\u0101jiena priek\u0161roc\u012bba paz\u016bd.<\/p>\n
Izr\u0101d\u012bj\u0101s, ka priek\u0161roc\u012bba melnaj\u0101m fig\u016br\u0101m ir \u0101rk\u0101rt\u012bgi neliela un gandr\u012bz neman\u0101ma.

Bartel\u0113mi apgalvo, ka tas pier\u0101da, ka pirm\u0101 g\u0101jiena priek\u0161roc\u012bba nav nejau\u0161\u012bba.<\/p>\n

Tas liecina, ka pirm\u0101 g\u0101jiena priek\u0161roc\u012bba ir nevis nejau\u0161a, bet gan stabila sp\u0113les struktur\u0101l\u0101 iez\u012bme,\u201d saka p\u0113tnieks.<\/p><\/blockquote>\n
Vi\u0146\u0161 uzsver, ka klasisk\u0101 \u0161aha galda izk\u0101rtojums \u0161\u0137ita lo\u0123isks un simetrisks vair\u0101k no vizu\u0101l\u0101, nevis matem\u0101tisk\u0101s god\u012bguma viedok\u013ca. Fig\u016bru s\u0101kuma izvietojums tika saglab\u0101ts paaudz\u0113m, pateicoties galda atpaz\u012bstamajai vizu\u0101lajai simetrijai, kas atviegloja sp\u0113les uztveri.<\/p>\n

Neskatoties uz 960 iesp\u0113jam\u0101m s\u0101kuma kombin\u0101cij\u0101m, da\u017eas no t\u0101m izr\u0101d\u012bju\u0161\u0101s lab\u0101kas par cit\u0101m. Bartel\u0113mi nor\u0101da, ka poz\u012bcija Nr. 198 ir visbilans\u0113t\u0101k\u0101, kur\u0101 abi sp\u0113l\u0113t\u0101ji ieg\u016bst p\u0113c iesp\u0113jas vienl\u012bdz\u012bg\u0101kus nosac\u012bjumus.
