Woods, making his first start since withdrawing from the Dubai Desert Classic in February, went out in 35 shots with two birdies and a bogey, before returning in 34 shots with three birdies and a bogey.
Even for Woods - the redshirted one who, with is unprecedented showreel, taught golf to ignore every barrier that had ever been there before - this seemed surreal.
The tournament scoreboard is here. He had 12 birdies and three bogeys overall to get to 12 under for the no-cut tournament, three strokes ahead of Jordan Spieth and Tommy Fleetwood.
"I thought I did great", he told broadcaster Sky Sports.More news: YouTube Unveils Its Own Stories-Like Feature With 'Reels', Revamps Community

If the 41-year-old had stirred the memory bank with his first-round 69, then with three birdies in his first four holes, he switched on the mixer and made all the high-points of his career suddenly pour over back into the consciousness.
He bounced back superbly from that disappointing end to the front nine, though, with birdies on the 10th, 13th and 14th, before a wild tee shot on the next led to that penalty drop and a second bogey of the day. I blew a lot of them past the hole.
"The only thing I struggled with was the speed of the greens".
Fleetwood's countryman Justin Rose (68) was alone in fourth on eight-under, with Woods a stroke back alongside Matt Kuchar and Rickie Fowler, who both shot 70s, Japan's Hideki Matsuyama (66) and Italy's Francesco Molinari (68).
