I tried using the guide but that didn’t help any. I usually stay on 18 and hit on anything lower if it’s on the first two cards. You’ll only have 1bout 3/10 of getting A-3. If you have 3 cards and you’re a 17 and 16 then I’d stay. But if he;s packing an ace weigh it. I believe gable bot stays at 17. So if he hits a 16 he’s got 1/2 a chance of not busting on his next card. You know… if it was fair and all.
