Actually, this kind of tactical coordination is very common in horse racing, and for the Chen brothers, it's nothing new. They have used this tactic many times in official races to defeat many strong competitors, executing it with ease.
But for today's race, being forced to use such a tactic is actually quite disgraceful.
Because this is not an official race, and their opponents are not professional jockeys, not to mention that the opposing mounts aren't even well-trained racehorses.
Yet under these circumstances, the Chen brothers were pressed by their opponents to resort to such a tactic. If word of this got out in the horse racing community, the brothers would definitely lose all face.
However, they are now retired, and this race involves a bet of several hundred million, so they have no way out. Even though they know it's shameful, they have to do it.
