(assume 7-point games)
If you're playing trifectas, and planning for a particular post to run out, these combos are more likely than those where a (potentially long) playoff is necessary. For example, the following post-win sequence:
produces a 7-4-1 trifecta, without a playoff.
How many of these can you find? Is there a pattern? Do you cover them all when you suspect a runout?
Hint: There aren't any for runouts by posts 1 thru 4.
