A group of four players, including Ian Poulter, are tied for the lead at the halfway stage of the Turkish Open.
Poulter produced a bogey-free round of 66 to earn a share of the lead alongside world number three Henrik Stenson, who shot a 65.
France's Victor Dubuisson and South Africa's Justin Walters also sit on 12-under-par, but they hold just a one-shot advantage over Tiger Woods.
The world number one wowed the Turkish crowd with nine birdies in a round of 63, to leave the American perfectly placed to challenge the leaders during the third round.
Jamie Donaldson is three shots adrift of the lead on nine-under, while England's Lee Westwood remains in contention in a tie for ninth.
