国际象棋必知英语词汇(六)


Today let's talk about a chess tatic named overloading.


过载   overloading 或 overworking


Sometimes a chess piece is overloaded by having more than one defensive job to do. The overworked piece can be exploited by capturing one of the pieces it is defending or occupying a square it is defending forcing it to leave its other defensive job.


简单说,过载通常指一个防御的子保护着多个子或者格子,难免无法面面俱到,护了一个就护不了另一个。我们举几个例子:



The black pawn on c6 wants to try to defend two pieces, but cannot!  Both pieces are under attack.

So, we can Nxd5, ...cxd5 and Bxb5, white win a piece.


The pawn is overloaded.  When white captures the bishop and the pawn recaptures, no one guards the knight!  The white bishop will take the knight for free.



Another example:

上面一个例子是一个子同时保护两个子,很容易顾此失彼。下面这个例子是保护着一个子与一个格子,同样很多时候无法兼顾,道理是一样的。



As you can see, the white queen is overloading. It is defending a bishop on c4 and a checkmate square on h1.

So, black can move Rxc4, if Qxc4, then Qh1# checkmate!



Try more examples of chess overloading.

Which piece is overloading?


White move first.

The black rook, which is defending the knight and the checkmate square e8.

So, white can move Bxc3.


Black move first.


The white rook on c2, which is defending the rook on c3 and stopping the pawn move to a2 threatening a promotion.

So, black can move a2.
