Standalone Pattern Set 4.s.12 in Connect 4
Connect 4 in 4 Moves
Deduction Path: Empty Sharing Fork Sub-Top with Topping of the Not-Winning Shared Re.
Sub-Top indicates the first forked pset, as mentioned under deduced from pattern sets, is the sub pset and the top pset is the second forked pset. The concerned re of the sub forked pset is just under the concerned re of the top forked pset as they share the same column. The depth of the sub re remains unchanged. The depth of the top re increments with one. For example re0 increments to re1. The topping clause indicates which re of the top pset is concerned and thus incremented.
Number of Patterns: 3
Pattern List: re0ppp, re1re0pp, re2re0pp
Deduced From: re0ppp, re0re0pp, re1re0pp
Best Defence(s): re0 of re0ppp
After playing a best defence move on one of the forked pattern sets specified under deduced from pattern sets hereunder this forked pset is disabled and the other forked pset remains active, in case of a siding fork, or becomes active, in case of a sharing fork, providing its winning move. In case of playing a best defence move outside of both forked pset's, both forked pset's remain active providing their winning moves.
Deduced From Pattern Sets:
Pset 1.s.1 (re0ppp, Winning Move: re0 of re0ppp, Deduction Path: Disc Omission on Pattern)
Pset 3.s.5 (re0re0pp, re1re0pp, Winning Move: re0 of re1re0pp, Deduction Path: Disc Omission on Both Patterns)

Condition List:
- 22EmptyTwoEqual: A rotatable empty (re) position of the first pattern of the concerned pset is on a same column as a re of the second pattern of the concerned pset. The other re of the first pattern is on a same column as the other re of the second pattern. In other words the two patterns of the concerned pset have two pairs re's sharing a same column.
- 122WinningNotWinningEmptyEqual: The winning re of the first deduced from pset is on the same column as the not-winning re of the second deduced from pset because this is an empty sharing fork with topping of the not-winning re.
- AfterTwoMovesNoFasterWinForOpponent: After any of all the opponents best defensive move(s) and then the players subsequent winning move(s), as specified by the winning move property of the concerned deduced from pset, no pattern set (pset) of the opponent may exist on the board that implies a faster win for the opponent. For example for psets 4.x.y (connects 4 in 4 moves) no psets 1.v.w (connects 4 in 1 move) of the opponent may exist after all moves specified above.
