Local casino only has H17 DAS no surrender games. My current plan is a 1-10 spread with $5 units using Hilo, wong in at TC+4 when <50% of the shoe has been dealt and at TC+2 if >50% has been dealt and wong out at TC-1. Betting $5 at TC -1 through +1, $10 at +2, $25 at +3, and $50 at +4 and up, is this a good winning strategy?
