Win in Pente, but loss in gomoku (and vice versa)
Posted: Jul 20, 2022, 9:30 AM

Aside from the obvious winning by 5 pairs captured rule (which some Pente players don't play with) Pente and gomoku have enough other differences to allow for positions which win in one game but not in the other one.
Thanks to pente_gon for this example position where white (player 2) wins in gomoku due to overlines not winning, but would lose from the same position in a Pente game:

A relatively simple example of a game position where one player would win in gomoku but the other player has the win in Pente (which doesn't involve winning by capturing 5 pairs) is the following game:


(from the position at 9. ... K5, or if 12. ...M7?? had been chosen)
Many of the game and position examples posted in the thread Pente Challenge- How to answer a open 3 by not blocking it would also be a win for one player in Gomoku (if the differences in numbers of stones for each player are ignored) and the other player in Pente.

It wouldn't be a position which could be arrived at in a gomoku game, but if the different numbers of stones for each player are ignored, then the example game below shows a fairly basic structural difference between Pente and gomoku in terms of who is winning at move 10. L13
