Marc Marquez soaked up pressure from his brother Alex to win MotoGP's Dutch TT sprint, further extending his championship lead.
It now stands at 43 points, following what was the 10th straight Marquez brothers sprint 1-2 in this season’s 10 events so far.
Marc had qualified only fourth, but a phenomenal start meant he was marginally ahead of poleman Fabio Quartararo for the lead exiting Turn 1.
Quartararo squeezed him out onto the outside kerb, forcing concertina-effect check-ups through the pack, but Marquez shrugged it off, staying with Quartararo through the lap and lunging past him at the Geert Timmer chicane.
His brother Alex followed through immediately at Turn 1, and a lap later Marco Bezzecchi - who had found his way past the traditionally sprint-limited Pecco Bagnaia - picked off Quartararo at the chicane, too.
Yet though Bezzecchi's early pace looked potent this would prove another all-Marquez show.
With Assen not one of his favourite tracks, Marc was consistently being reeled in by Alex through sector three - featuring three left-handers, including Duikersloot, at which Alex had half a look down the inside on the fifth lap, only for Marc to quickly shut the door.
And generally, the younger Marquez just couldn't compensate for the time he would then lose in the fourth sector - so something of a stalemate was quickly established, especially as both soon found themselves with track limits warnings.
No further attack from Alex was forthcoming, the pair finishing 0.351s apart, with Bezzecchi completing the podium behind him.
Quartararo was running fourth and looking good value for it when he crashed out at Mandeven, consigning Yamaha to a point-less day.

It promoted Fabio Di Giannantonio to fourth place instead, the VR46 Ducati rider having picked off Bagnaia at the Geert Timmer chicane - with Bagnaia's fifth place leaving him 117 points off the championship lead.
Maverick Vinales led KTM's charge in sixth, finishing ahead of Pedro Acosta on the road - though a track limits time penalty dropped Acosta behind Fermin Aldeguer (who served a track limits penalty of his own during the race) and Franco Morbidelli.
Acosta still held on to the final point by 0.074s over team-mate Brad Binder in the classification.
Morbidelli's race has been compromised on the opening lap, as team-mate Di Giannantonio went around his outside at Ossebroeken and hugged the inside kerb after the change of direction for Stekkenwal - with Morbidelli seemingly caught unawares and forced to pick up his bike and run wide.
His day was at least recoverable, though, whereas Raul Fernandez - who got caught up right behind him and had to go deep into the gravel - was effectively out of the fight and parked up shortly thereafter.
The race's only other retirement had already occurred at that point, Joan Mir going wide at Ossebroeken and losing the front.
