Fog played havoc with Thursday's first-round play -- Jaidee only got one hole in before play was called off -- and caused a backlog that left many golfers unable to get their second round in.
As a result, organizers cut the tournament to a 54-hole event, with the remainder of second-round play set for Saturday. The tournament is to wrap with 18 holes Sunday.
Marcus Fraser, who led after Thursday's play with a 7-under-par 65, was among those who didn't get on the course Friday.
Jaidee and Goya are at 8-under-par 136 after 36 holes. Brett Rumsford also finished two rounds and is tied with Fraser at 7-under. Mark Foster, who also wasn't able to play Friday, is at 6-under and alone in fifth place.
Jaidee had five birdies and a pair of bogeys in his first round and seven birdies and a double bogey -- taking a 6 on the par-4, 460-yard sixth hole -- en route to his share of the lead.
Goya, despite three bogeys in a five-hole span, turned in a second-round 2-under 70 after he finished off a first-round 6-under 66 earlier in the day.
