If Cooperators play together nicely by staying out of each others' draw ranges, Cannibals do exactly the opposite by getting
in each others' way.
A Cannibal card adds value to one row's primary draw or EV while simultaneously subtracting value from another row
because it reduces the number of primary draw outs and/or immediate scoring value in that row.
This starting hand will in most circumstances be split in the first-five set
to draw to a back row flush or a full house+ (see below), but in either set,
the 5 of spades is a cannibalizing card.
Setting the 5 in the back row with the other spades allows for a back row flush-draw EV, but reduces immediate scoring value
and the drawing range of the middle row:
Alternatively, setting the 5 with the other 5's allows the boat+ EV, but again reduces immediate scoring
value and the primary draw range for the middle row:
When playing standard OFC, the trips back row set probably makes the most sense; in Pineapple OFC, not necessarily. Setting
trips in the middle and a 2-flush in back isn't a bad play with 12 cards coming, if the quality of the array
is good. [ See Parts I and II for discussion of the array ]
Cannibals can also appear on subsequent streets any time the first five cards are not able to be set in fully cooperating
draw ranges. The following pull on 8th street is
an example of a typical setting conundrum:
If the 7s is set in the back row, it adds value to the flush draw while simultaneously eating the middle rows' primary drawing outs,
weakening the hand's chances of getting to Fantasyland; if it is set in the middle, foul probability jumps in the back row. Again,
the variant of the game makes a big difference here. In standard OFC, the only play is to set the 7 in the back row. In Pineapple,
depending on array quality, the middle row is a likely destination.
