Kristoffer ends the game, but does not win it

Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.

Kristoffer puts a K in B5, then a K on C5. On his final turn, he decides to end the game and leave Espen with zero points by placing an E in E3, completing three-in-a-row. At the end of the game, he has two pieces on the grid, and receives only 2 points.
