I agree with this. I do see this kind of instaship by amateurs. They tend to bet size poorly, either way underbetting the nuts or way overbetting the nuts.

I am exaggerating the "never" part, but it's safe to say that mass majority of times an insta shove is a premeditated move before the street.

Most players just don't have the time to insta-process a card that turns your hand from vulnerable to near-nuts or perceived nuts as it is the case in this hand.

If she plays every street at almost instant speed and it's a norm for her, then perhaps I can reason that she is capable of processing information at such quick speed, but I doubt that to be the case here.

As for you guys' examples that people insta-ship with nuts. I am willing to bet that those cases were nuts before action, not insta-ship upon seeing the nuts, or maybe an instant to you is slightly longer than what I consider to be an instant.

But what the hey, we're arguing reads here, so it's not like there's right or wrong answer.
