(Reuters) - German Martin Kaymer stayed on course for a fourth title at the Abu Dhabi HSBC Championship with a second consecutive round of 66 to seize the halfway lead on Friday. The straight-hitting Kaymer again found the course and conditions to his liking to move one stroke clear on 12 under. Spain's Rafa Cabrera Bello also carded a six-under 66 to move to 11 under for his two rounds.
