|It's Halloween Knight!|
The Halloween Gambit, or Leipzig Gambit, is an aggressive gambit in chess, in which White sacrifices a knight for just one pawn. There are many different kinds of gambits, but the usual aim of a gambit is to obtain an advantageous position after giving up material as white. This gambit is related to the Four Knights Game and may transpose easily if your opponent is not cooperative. It was proven in 1888 to be an unsound opening meaning that you should not use it.
