Occasionally, I will bet Miami's superfecta on certain games,
when I like a team a lot, especially Goiko in post 8 with Erkiaga
or Irastorza. It can get a little pricey, but the keyed numbers
off post 8 are very easy to call, such as 8/12/4567/4567. What
makes it really exciting is if you are fortunate enough to hit
the superfecta, often, the combo looks tough, but really isn't,
like an 8-3-7-2...a run number that comes in more than some think,
and as a result, pays very large.
