If you kinda stumble upon the nuts by the time you're on the river, and as such the pot is really small, say 100 bb stacks an 12 bb in the pot, are you better off shoving every time rather than say an 8 bb value bet?

If we assume say 1 in 2 value bets are called, thats an extra 4 bb per time, so if even 1 in 25 100 bb shoves are called it is more +ev. And shoving over such a small pot looks like you don't know what you're doing, which surely must help lead to people calling.

Now perhaps the above figures aren't realistic, but I'm wondering if perhaps there is a particular min stack and stack to pot ratio that would make the above concept true.

Any thoughts?
