Part 3 is devoted to A-Chess, where any game is finite as a game is stopped with some result.\u003c\/p\u003e\u003cp\u003eWhile I-Chess analyzes mostly infinite games, A-Chess analyzes only finite objects: either finite games (as games finishing by a final position) or finite segments, finishing by not a final position. Finite segments of games (or even finite games) are caused by the action of “Stop”, a special procedure of stopping (ending) a game. “Stop” is one of the two features of A-Chess.\u003c\/p\u003e\u003cp\u003e3. A-Chess has a System of Values (SV), which offers values of positions. A value of a position is a specific number attributed to the position in a case of stopping a game and affecting the result of a game. System of Values is also one of the two features of A-Chess.\u003c\/p\u003e\u003cp\u003e4. In general, A-Chess (which may be called Human A-Chess) allows action of numerous and different rules of Chess, stipulating an end of a game and System of Values. Some of these rules directly depend on human factors (for example, resigning or agreeing a draw); some others depend on the specific rules of Chess (for example, three times repetition rule or “50 moves” rule).\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e","brand":"Ishi Press","offers":[{"title":"Default Title","offer_id":47063608230128,"sku":"9784871877268","price":99.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9784871877268_p0.jpg?v=1763714545","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9784871877268","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
