Not sure if this applies to all games. But I played some Speed cash games lately and whenever I try to get all in, I just slide the bet slider all the way to the right. However, for some reason it seems to just jump back a little bit, meaning you leave like 1bb behind.
I've had this happen to me, and see this very regularly at the tables, where people randomly leave a couple cents behind when putting their money in (most likely accidentally).
This of course isn't really a big deal, but it's still strange. Anyone else experiencing this?
