Don did some work on this didn't he? But really, depends on circumstances. How nearby is another better opportunity? 5 feet at the next table? 5 minutes at the next (nearby) casino? Or an hour drive to the next casino?
With my answers being 5 feet to the next table, or 5 minutes, or even 10/15minutes to the next casino, I just am not interested in playing through many negative counts. I often hear that logic that you shouldn't bail too early because the count still could "turn around". Describe "turn around" because I am not just looking for the count to "turn around" and go from negative to positive. I am looking for 'Max Bet' opportunities, and preferably early in the shoe so there can be many rounds played at that max bet opportunity. That is far less likely to occur once the count goes negative.
Bottom line: Given the choice of a moderate negative count, let's say running count -7 with 5 decks remaining (TC -1.4), or a fresh game (running and true count zero), I am
always opting for the fresh game. And for me, there is always a fresh game nearby somewhere.
