Computer Hand poker
1) Any hand that computer analysis/simulation determines is
positive but turns out to be difficult to play in practice.
2) In hold 'em, Q-7 as one's first two cards. Comes from an
apocryphal story that "someone" did an extensive computer
simulation of hold 'em hands in which those two cards appeared
most frequently in the flop, or, in some stories, among the
down cards.
The simulation was atypical, however, because the chances are
the same for any two cards of different ranks.
