Pablo Larrazabal shot a 4-under 66 on Friday to join fellow Spaniard Miguel Angel Jimenez in the lead of the European PGA Tour's KLM Open.
First-round leader Jimenez shot a bogey-free 67 to stay in the joint lead of a tournament he won in 1994. Both players had 9-under totals of 131.
"This course suits me," Jimenez said "It's not a very long course but you have to have the ball in position."
The 49-year-old veteran is chasing his 20th European Tour title.
Larrazabal briefly held the outright lead before he bogeyed the 16th.
Three-time champion Simon Dyson matched the course record at the Kennemer Golf and Country Club with a 63 to join fellow Englishman Oliver Fisher and Julien Quesne of France a shot behind the leaders.
Dyson won two of his Dutch titles on the links-like Kennemer course on the Dutch North Sea coast and the third in Hilversum.
"I've done well in previous years and played well around it today," he said.
"I played really solid apart from the last two holes and never looked like making bogey."
So far, his only dropped shots of the week came on the first hole of the first round, when he double-bogeyed the par 4.
Another Spaniard, Jorge Campillo, also shot a 63 with six birdies on the front nine to be at 6 under in a tie for seventh. He looked on track for a course record, but had a three-putt bogey on the 18th.
