In Professional BJ by S. Wong is written: "The bet scheme is 100 a couts per dech of +4 or more,75 at +3, 50 at +2, 25 at zero or +1, and 10 all negative counts." (Benchmark Rules)
My question is: why I have to bet 25$ at count per deck zero? That means that if I don't change my bet value (no spead) I always win.
Thank you.
