If you change horses at the beginning of the game, it is definitely a big loss. If you use two cannons to knock down the opponent’s two horses, if both sides are weak in chess, then the outcome of this game is not certain, and you can continue to play. If both parties are provincial or municipal or master-level masters, then the outcome of this chess game has been divided, and the first player will undoubtedly lose, there is no suspense. From the basic chess theory, you defeat the opponent’s two horses, and the opponent eats with the two carts. Shuangpao exchanged two horses for two pieces, and both sides took two moves, but the back player took this opportunity to make two moves, which is an effective move and takes two more moves than the first player. But the first move is equivalent to not taking a step, and it has fallen into a disadvantage. From the efficiency of the game, there are already two net losses. Any chess player with a certain level of chess knows that it is definitely not a small advantage for the side holding the two firsts. National chess masters and special-level masters are only two firsts against listed-level masters. For example, in the Baby Cup Chess Master Invitational held in Shanxi in recent years, there has been a game where the masters made the city-level masters two first. From the point of view of the value of the pieces, the value of the artillery is greater than that of the horse in the middle of the game. The horse is a middle-range combat pawn, and the artillery is a long-range combat pawn. In the opening stage, a horse needs a lot of steps to go from its own position to the enemy’s position. In the opening stage, the elements are crowded and easily hindered by soldiers and other obstacles, so they can’t exert their power in all directions. Compared to horses, artillery is much more flexible. Act quickly, come and go freely, and can exert a powerful force in the opening midgame. Coupled with the advantage of two vehicles coming out early, two vehicles, two artillery and four-character joint operations, how can the opponent resist? The above is the conclusion drawn from the analysis of the basic chess theory.
