English pair Robert Coles and Richard Bland are tied with Carl Suneson of Spain and South African Hennie Otto going into the final round of the Daewoo Warsaw Open in Poland.
After a protracted day, which began with a 45 minute delay for fog, Coles carded a bogey-free 68 for 209, four under par, to set the target only to be caught, first by Suneson and Bland, who were playing together, then by Otto, all three returning 70.
The quartet is a shot ahead of Didier de Vooght of Belgium, another with 70, and Benoit Teilleria of France, who went round in 71.
Coles, 27, from Hornchurch in Essex and a keen soccer fan of West Ham, began the day three strokes off the pace but did well to avoid dropping a shot on a tight, treacherous course where the many water hazards and towering trees gather balls like a magnet.
Bland, 26, from Southampton, dropped only one shot in his 70 and said: "I didn't really hole a lot but when I missed a green I usually got up-and-down safely."
Suneson, with three victories already under his belt this summer and current leader of the rankings, got to six under at one stage, two clear of the field and looked set to lead at the end of the day. But three bogeys in four holes from the 13th dropped him one behind before a birdie-four at the 17th ensured he starts on level terms with his rivals tomorrow.
"It's going to be an interesting final day," he said. "A lot of people are going to be nervous out there, thinking of their card or getting into the top 15 on the rankings. Anything could happen but experience might count in the end."
Otto, who finished joint second in Russia two weeks ago, dropped three shots early on but recovered well while birdies at the 14th and 15th brought him home in 70 for a share of the lead.
It would have been an even more congested leaderboard but Sweden's Per Magnebrant bogeyed the final three holes for a 74 and 213.
But it wasn't a good day for overnight leader Iain Pyman. Staring one clear, he found four bogeys in a 73, which would have been worse, but for a birdie-four at the long 17th. It leaves him in seventh spot on 211, two behind the leading quartet.
The best return was a 66 from Sweden's Ola Eliasson, who was five under after 10 holes but couldn't squeeze out any more birdies. It leaves him in eighth place on 212.
