Maneuver: When an opponent attacks his weak chess, he tries to play chess within the opponent's sphere of influence, which is similar to playing chess, but the difference is that playing chess is mostly used to represent big pieces, while playing chess is mostly used for several pieces, because the purpose of maneuvering is not to live all the pieces (because there are not many pieces to discard), so when playing chess, he tries to find opportunities to do it by touching, leaning and breaking. Generally speaking, you don't need all the work, you only need a part to break each other's air.

Strong hand: local strongest reaction, contrary to steady hand, is a tough means to seek the greatest benefit, but it is not as concise as this hand, and computing ability is the key to the success of strong hand.
