Standalone Pattern Set 4.s.17 in Connect 4
Connect 4 in 4 Moves
Deduction Path: Empty Siding Fork with Two Defensible Re's Different and Re1ppp Shared.
Defensible re is the re of the concerned pset the opponent could defend upon at least if it were the opponents move. Just suppose the opponent is going to move on the concerned pset. If he moves on the defensible re he effectively destroys the players pset without transforming the pset to an even faster win for the player.
Number of Patterns: 3
Pattern List: re1ppp, re0re0pp, re0re0pp
Deduced From: re1ppp, re0re0pp, re1ppp, re0re0pp
Best Defence(s): different from all re1's of the pattern list
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 3.s.2 (re1ppp, re0re0pp, Winning Move: re1 of re1ppp and re0 of re0re0pp different from re1 of re1ppp (from identical pset 3.s.4), Deduction Path: Disc Omission on Pattern and on Depth of the Other Pattern)
Pset 3.s.2 (re1ppp, re0re0pp, Winning Move: re1 of re1ppp and re0 of re0re0pp different from re1 of re1ppp (from identical pset 3.s.4), Deduction Path: Disc Omission on Pattern and on Depth of the Other Pattern)

Condition List:
- 12EmptyOneEqual: The rotatable empty (re) position of the first redppp pattern of the concerned pset is on the same column as a re of the second red1red2pp pattern. In other words the two patterns of the concerned pset have one pair re's sharing the same column. The other re of the second pattern is on a different column.
- 12EmptyOneEqual: The rotatable empty (re) position of the first redppp pattern of the concerned pset is on the same column as a re of the second red1red2pp pattern. In other words the two patterns of the concerned pset have one pair re's sharing the same column. The other re of the second pattern is on a different column.
- 122TwoDefensibleEmptyDifferent: One defensible re of the first deduced from pset is on a different column than one defensible re of the second deduced from pset. The other defensible re's of the deduced from psets are shared.
- 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.
