Catch Perfect poker
Make precisely the hand you're drawing to. In lowball, if you're
drawing to 8-4-3-2, and catch a 7, 6, 5, or ace you make your
hand; if you catch precisely the ace, you catch perfect. In
high draw, if you start with 4-5-6-7, all in diamonds, and catch
any diamond, you make a flush; if you catch any 3 or 8, you
make a straight. If you catch either the 3 or 8 or diamonds,
you make a straight flush, and you can say you have caught perfect.
The term is also heard in hold 'em, in a situation in which
only one or two cards remain that will turn a losing hand into
a winner.
