Do you like chess? How about Japanese chess? Aren't there different chess variants in Japan though? Maybe, but this specific chess variant is called Shogi. The chess-like game Shogi is won by capturing the king, just like chess, but defeat is conceded at mate, or when mate becomes unavoidable.
This video tutorial gives you a lesson on how to checkmate the king on the Shogi board. This is a really good description of check and checkmate, and there's also an exercise problem for checkmating your opponent's king. If you already know how to read the Chinese characters on the Shogi pieces, then you'll fly through this lesson like it's nothing. You won't believe how similar Shogi is to actual chess.
