What is Legal's Mate?
国际象棋中Legal的搭档是什么？这是一个开放式陷阱，以华丽的女王牺牲为特色。白方允许黑方吃掉后，用两名马和一名象完成了令人惊叹的两步将死。
How It Works — Step by Step
The pin that enables the trap
Black has just pinned the f3-knight against the queen with Bg4. The pin looks strong — but it is exactly the precondition for Legal's Mate. White is about to demonstrate, in spectacular fashion, that the 'pinned' knight can move anyway.
Nxe5!? — the queen sacrifice
White ignores the pin and plays Nxe5!, apparently leaving the queen hanging. If Black greedily grabs it with Bxd1, the trap snaps shut. The correct reply is Nxe5! — taking the knight, not the queen — after which White has nothing better than regaining the piece. This is the critical moment.
Bxf7+ — the king is dragged out
Black took the queen — now comes the punishment: Bxf7+!. The bishop is protected by the e5-knight, so the king cannot capture it. Ke7 is the only legal move, and the black king is dragged into the mating net.
Nd5# — checkmate
Nd5# — checkmate with three minor pieces. Every escape is covered: the f7-bishop seals e8 and e6, the e5-knight guards d7, the d5-knight covers f6, and d8 is blocked by Black's own queen. The queen 'sacrifice' was never a sacrifice at all.
Common Misconceptions
Legal的杀是一个万无一失的把戏，总是能赢得皇后或游戏。
这并不是万无一失的。如果白方没有正确准备（通常先下h3），黑方可以用...Nxe5 来回应Nxe5。黑棋没有拿走皇后，而是赢得了完整的棋子。

Frequently Asked Questions
Everything you need to know about Legal's Mate
列戈尔的将杀是一个涉及女王牺牲的开放陷阱。白方允许黑方吃掉后，用两名马和一名象强行将死两步棋。
你可以通过允许对手用他们的主教钉住你的f3骑士，然后用Nxe5牺牲你的女王来做Legal的配合。当他们拿下皇后时，你先玩 Bxf7+，然后玩 Nd5#。
不，列戈尔的杀并不总是有效。如果白方在没有适当准备的情况下下 Nxe5，黑方可以简单地下...Nxe5。这样既保护了主教，又让黑棋留下了一块棋子。
