Did this shot skid?

The 7 ball right? Naw, it was just a difficult shot under pressure and he missed. Skids always result in an undercut, not an overcut.
 
Can any of you tell me what causes an object ball to skid. It has happened to me a few times but I haven't been able to figure out the constant that is causing the skid.

Don't mean to hijack the thread, just didn't want to start a new one.

It is possible to induce skids by applying chalk to the balls. It has been observed that when more chalk is on the balls (such as Kamui beta version), there are more skids. It has been calculated that the frequency of skids is consistent with the area of chalk spots that are on the typical cue ball. After skids, chalk scuffs and chalk have been observed on balls. None of this is proof of the guilt of chalk on balls, but I think a prosecutor would get a conviction from any reasonable jury.

It's caused by extra friction between the cue ball and the object ball. If one or both of them are unusually dirty and sticky they don't slide off each other the usual way. The cue ball will briefly grip or rub the object ball, shoving it a little in the direction the cue ball is already moving. Hence the ball undercuts.

In extreme cases a rolling cue ball will even climb up the face of the other ball, leave the table briefly, then plunk back down. This is the cause of the loud clack or thud sounds you sometimes get on a bad skid, it's the cue ball coming back down and hitting the table.

If you google Dr Dave billiards skid you can see a video of it in his site.

I'm fairly new to pool so my eyes aren't well enough trained to know if this shot of AlexP's was a skid, or just a miss?

Hopefully this link will take you to the replay with a good angle-view of the shot:

To me it looked like it did skid some.(didnt start to roll correctly)
But the skidding was actually helping him because he over cut the the ball.
If the ball starts rolling correctly he would of missed it worse.

This is not true. If you have "excess" side spin, an skid can produce an overcut.

As for that happened on Alex's nearly straight shot on the 7, if you notice the spin on the cue ball in the slo-mo replay, the cue ball arrives at the 7 with stun (no follow or draw) and a little side spin. That is a combination that maximizes normal throw. If he had played the same shot with a touch of draw, the shot would not have thrown as much.

Looks like he just played a slide shot in order to kill the cue ball, and he misjudged it.

yep. I know this is called a drag shot also, maybe in Byrne's books or somewhere else.
That's the same very thing I suffer from sometimes. With this type of shots you want to hit the cue ball with no side. And when you fail to accomplish that, i.e. apply some English, the cue ball simply swerves from straight path right after the draw kills and transfers to follow. So that results in a miss, as simple as that.
The shot pictured did not skid.
 
My English is not the best, do you use the term "skidding" in the sense of "sliding" or "gliding" or in the sense of "kicksing" (bad contact between balls; balls "snag" caused through dirt)?

In the context of this thread a skid is bad contact between the balls, usually caused by chalk on the cue ball.

I'm learning a lot about this. I thought the problem was chalk on the table, but most of the replies refer to chalk on the cue ball.
