Denmark's Soren Kjeldsen holds the clubhouse lead at the KLM Open, but with over four hours lost to thunderstorms the halfway lead will not be decided until Saturday.
Danes dominated the leaderboard as first round joint-leader Anders Hansen finished a disrupted second round with a 73 to finish one shot behind his compatriot.
Kjeldsen's three-under 68 took him to six-under 136, a stroke ahead of Hansen and Ireland's Damien McGrane, who shot 68 in the morning session.
Spain's Ignacio Garrido had reached eight-under but still had seven holes to play when play was called off for the day at the Kennemer Golf Club.
Tournament favourite Colin Montgomerie, one of the players warming up for next week's US PGA Championship, looked as though he would miss the cut when he played on after the suspension but rallied with four back nine birdies in five holes to lie two-under with just one hole to finish.
Paul McGinley protected his endangered tenth place on Europe's Ryder Cup table by making the cut on level-par 142 after a 70 but his rival Paul Broadhurst missed the cut on seven-over after a 76.
