Problem: (CNN) -- China is proving home from home for Novak Djokovic as he demonstrated yet again by rebuffing the considerable challenge mounted by Juan Martin Del Potro to retain his Shanghai Masters title Sunday in another three set classic.

Last year Djokovic also went the distance to beat Britain's Andy Murray in a riveting final rated as one of the best matches on the ATP Tour in 2012, this time around he showed all his battling qualities to see off the Argentine ace 6-1 3-6 7-6 at the Qizhong Tennis Center.

Sixth seed Del Potro had stunned new World No.1 Rafael Nadal in the semifinals, but could not repeat these heroics despite forcing a third set.

Neither player could gain the crucial break of service in the decider, but Djokovic opened up 2-0 and 4-2 leads in the tie-break and won the title with a backhand winner down the line after two hours 33 minutes.

It was his seventh of the season and came hard on the heels of winning the China Open last week where he beat Nadal in the final.

He paid tribute to Del Potro after his latest triumph. "He's a fantastic player and a great person," Djokovic told the official ATP Tour website.

"All the way up to the last point, I didn't know if I was going to win the match. It was a very even match. My motivation is there always, especially when I'm playing finals of such a big event."

The 26-year-old was winning his 20th straight match on Chinese soil and he improved to 62-9 for the season.

Problem: CHAPTER XXXVI.

BATTLE OF BLACK RIVER BRIDGE--CROSSING THE BIG BLACK--INVESTMENT OF VICKSBURG--ASSAULTING THE WORKS.

We were now assured of our position between Johnston and Pemberton, without a possibility of a junction of their forces. Pemberton might have made a night march to the Big Black, crossed the bridge there and, by moving north on the west side, have eluded us and finally returned to Johnston. But this would have given us Vicksburg. It would have been his proper move, however, and the one Johnston would have made had he been in Pemberton's place. In fact it would have been in conformity with Johnston's orders to Pemberton.

Sherman left Jackson with the last of his troops about noon on the 16th and reached Bolton, twenty miles west, before halting. His rear guard did not get in until two A.M. the 17th, but renewed their march by daylight. He paroled his prisoners at Jackson, and was forced to leave his own wounded in care of surgeons and attendants. At Bolton he was informed of our victory. He was directed to commence the march early next day, and to diverge from the road he was on to Bridgeport on the Big Black River, some eleven miles above the point where we expected to find the enemy. Blair was ordered to join him there with the pontoon train as early as possible.

This movement brought Sherman's corps together, and at a point where I hoped a crossing of the Big Black might be effected and Sherman's corps used to flank the enemy out of his position in our front, thus opening a crossing for the remainder of the army. I informed him that I would endeavor to hold the enemy in my front while he crossed the river.

Problem: CHAPTER XXVI

A NEW UNDERTAKING

Soon after the rails were laid down the frost returned, and one cold morning Festing sat in his shack, studying a letter from Helen. Norton's cheque had helped him to overcome the worst of his difficulties, things were going better, and Charnock would superintend the workmen until he was ready to go out. Festing felt that he need not hurry, and wanted to think.

Helen had written to him before, without any hint of resentment, and he had told her what he was doing. She knew Bob was his partner, and no doubt understood what this implied. It was obvious that he had been wrong in disliking Bob and half suspecting him; besides Helen knew from the beginning that he had not suspected her, although he had insisted that she had been imprudent. This ground for difference had vanished, but he wondered what she thought, and could not gather much from her letter.

She wrote with apparent good-humor and stated that all was going satisfactorily at the farm, where, indeed, nothing of importance could be done until spring. For all that, there was some reserve. A personal explanation was needed before they could get back to their old relations of intimate confidence, and he was ready to own his mistakes. Unfortunately, the explanation must be put off, because there was one point on which he was still determined, although his resolve no longer altogether sprang from pride. He must, if possible, repair his damaged fortunes before he went home. Farming on a proper scale was expensive work, and Helen's capital was not large. In order to raise a big crop, one must speculate boldly, and he meant to do so with his own money.
