Jorge Campillo insists he will not be changing his approach after securing the top seeding over the first two days of the Belgian Knockout.
The field played 18 holes of stroke play on days one and two at Rinkven International Golf Club, with Campillo carding back-to-back rounds of 67 to finish at eight under and lead the way by one shot heading into six rounds of nine-hole knockout stroke play over Saturday and Sunday.
The top 64 qualified for the weekend, with the top 16 players securing a seeding that means if their first round match finishes with the scores level, the seeded player will advance to the last-32.
England's James Heath finished a shot behind Campillo, one ahead of home hero Thomas Detry, Danes Søren Kjeldsen and Jeff Winther, Australian Dimitrios Papadatos and Frenchman Victor Perez.
Campillo is looking for his first European Tour win but has four top fives in his last six appearances and he brought that form with him to Antwerp.
He entered the day in a seven-way tie for the lead and was still in a share as he turned in 34 from the tenth, but he really found his form on the front nine. Birdies on the first and second moved him two shots clear and a wonderful approach to the fourth had him in control.
"I wish it was a medal play tournament in the position I'm in right now but it is what it is," he said. "Obviously it's better being on the top than on the bottom and you still have to win tomorrow.
"In medal match play you still have to be careful, you can have a high number on a hole and throw away a few shots in one hole so you still have to play the same golf. It's a nice format if you're playing good.
"I played solid both rounds. Yesterday I hit it straighter off the tee, today maybe I hit better irons but I'm happy with both rounds. Yesterday was a little tougher but today it was a little cold in the morning and it wasn't playing easy the first few holes so both rounds were quite similar."
Heath turned in 34 with birdies on the third, fifth and seventh and a single bogey on the sixth. Further gains on the 13th, 16th and 17th then put him in a share of the lead but he bogeyed the last.
Detry recovered from a bogey on the tenth with birdies on the 12th, fifth and eighth - the latter courtesy of a stunning approach to three feet.
Kjeldsen bogeyed the second but hit back brilliantly, birdieing the third and making a hat-trick of gains from the sixth to turn in 33. The 43 year old made another birdie on the 12th and while he gave the shot back, birdies on the 16th and 17th gave him the lowest round of the week with a 66.
Winther had closed within one shot of the lead thanks to birdies on the tenth, 17th and fifth but a bogey on the eighth saw him slip back.
Papadatos won last week on the Challenge Tour and he maintained that momentum, birdieing the eighth, 13th, 16th and 17th in a bogey-free effort.
Perez also plies his trade on the Challenge Tour and he started with a bogey but birdied the 11th, 14th, 16th, 17th and eighth.
England's Matthew Baldwin, Australians Nick Cullen and Marcus Fraser, Italian Lorenzo Gagli, Chilean Nico Geyger, Malaysian Gavin Green, Frenchman Benjamin and Spaniard Adrian Otaegui were all at five under.
Tournament host Thomas Pieters was at two under, one shot behind Nicolas Colsaerts and one ahead of Christopher Mivis to make it four Belgians into the knockout stages.
Swede Pontus Widegren became the first player since Miguel Ángel Jiménez at the 2015 Open de España and BMW PGA Championship to make a hole-in-one in consecutive weeks.
His ace on the 15th - coincidentally the same hole he needed just one blow on at last week's Rocco Forte Sicilian Open - was the 17th of season and came courtesy of a seven iron from 172 yards.
There was drama around the cut-line with an 11-man play-off for eight remaining spots seeing Australia's Jordan Zunic, New Zealand's Ryan Fox and Englishman Callum Shinkwin miss out on the top 64.
