解释
英格兰-印度防御始于白方 c 兵位于 c4，黑方 g8 马发展到 f6。这匹马控制 e4 和 d5，参与中心斗争，并允许黑方推迟决定兵形。
正因如此，英格兰-印度是一个总称。黑方可以继续 ...g6、...e6、...d5 或 ...c5，每种选择都会形成不同结构。白方可以选择 Nc3 或 Nf3，准备把象放到 g2，占据 e4，或推进 d4。行棋次序很重要，因为不同开局可能到达同一局面，这称为转位。
当黑方在 ...Nf6 和 Nc3 后走 ...d5，就进入 分支。其他后续会让局面在更长时间内保持未定。要理解这一家族，应识别黑方的第二个明确选择，而不能把 1...Nf6 当作完整计划。
用法与背景
这一标签适用于黑方尚未选定具体印度防御结构，或棋局仍保持独立英国式开局特征的阶段。
常见混淆
英格兰-印度防御与王翼印度防御
并非所有英格兰-印度防御都会成为王翼印度防御。后者还需要后续投入，通常包括 ...g6、...Bg7 和 ...d6。
