Are there endgames in chess?

There are a lot of rows in chess.
Let me give you a simple example

No.1

This super small platoon, its moves are also quite simple. 1.Rf3 g2 2.Bf1!  g1Q 3.Rh3# Undoubtedly, this bureau has demonstrated another method of killing the elephant and the car.

No.2

If you have received regular national elephant training, you must have come into contact with this exercise. It reveals an important factor in the endgame: the king's position.

1.Ba7!

Induce the black elephant to move away from a1-h8, which is a large diagonal line, to facilitate the ascension of the white soldier. Naturally, Black is not happy. I think so. It reveals an important factor in the endgame: the king's position.

1... Ba1 2.Kb1 Bc3 3.Kc2 Ba1

The White side is trying to improve Wang's position, but so far it seems to be a step too slow. What to do?

4. Bd4!!

It was brilliant, forcing Black to

4... Bxd4

then

5.Kd3 Ba1 6.Ke4

Bai Fang successfully carried out his plan.

No.3

Bai Xiansheng
This game is also poetically beautiful.

1.Nc6! Kc6 2.Bf6

1... a2 is definitely giving up the struggle, as White has 2.Nb4+
Black had to accept to abandon his horse. Now, it is certain that the white elephant is in a good position, but the black pawn in d4 is annoying.

2... Kd5 (2... Kc5 3.Be7+) 3.d3 a2 4.c4

No doubt, the black side will not be willing to eat the passers-by, but after all can not get rid of the fate.

4... Kc5 5.Kb7!

Blocking the Black Queen's exit, and hiding the murder.

5... a1Q 6.Be7#

A perfect shot.

No.4

The tactic of "leading away" was used, but before it was used, it was necessary to guard against a black counterattack.
Don't look at the answer first
