I know for a Las Vegas downtown game (1D, H17, DOA, noDAS), 8 vs 5,6 should be double down, and 10 vs 2-9 should also be double down. But how about (4,4) vs 5 and 6, and (5,5) vs 2-9, are these should be double down too?
Right on. For a hi lo counter you are seeing up to a +3 count. For a Hi Opt II counter you are looking at up to a +6 count, all good #'s for a DD, depending on what has come out prior, if any.
And get ready to leave a pile of your win out there too.
