US lose because they unironically think like you do.When you play chess, your goal is to protect your King, so you only look at your King, Queen, and the two pawns in front of it. You don't look at what your Rook, Knight, Bishop or other pawns are doing, or your opponent's pieces, because once you start looking at the other squares on the board, you get dragged into a complicated web of unrelated problems. There are so many pieces on the board and diversity, it is too complicated for your brain to handle. Remember how your opponent moved his Knight one day, and then his Bishop the next day. The important piece one day becomes the unimportant piece the next day right? It gives you a headache and you need to lie down. Might as well forfeit the game if it's that complicated. Here is a glass of water.
This is stupid thinking. The U.S. has put a target on China's back and will try to recruit the entire world into the game. So the entire world is the chess board now. There is no deal to be had between China and the U.S. Whether China acknowledges it or not, or wants to or not, other people's problems are going to become China's problems now. That is what happens when you are competing for #1 in the globe, or are targeted by #1 in the globe.
An amateur chess player looks for every opportunity to attack anywhere on the board, paying no heed to grand strategy, that most of his attacks waste his own time, put his pieces out of position and can easily be guarded by the enemy. A professional works towards tangible objectives.
While US is busy doing exactly what? Looking tough with 10 different mostly verbal threats every month and a few bombs on literal desert dwellers, China has more or less successfully taken out EU from the equation, it has checkmated India geopolitically through Bangladesh and Sri Lanka, and seen to that the Korean far right gets couped. All the while while keeping pressure on US economy high and keeping China's home economy untouched.
It don't matter if US try to bring the entire world against China. China has more money, resources and crucially also have smarter strategists. China will again just out gambit and out play US in most theaters. In chess there is such a thing such as tactics and sacrifices, and in weiqi there is an idea of flipping enemy colors through your tactics.
China will not meet every single US advance head on, because many US advances are stupid. Look at Iraq and Afghanistan for example. US did all the work killing and dying, then in the end they become yuan exclusive China resource outposts for free. And where China does meets US' advance head on, like in Ukraine, China will sweep US aside using its sheer size advantage.
