Six-time champion Ronnie O'Sullivan extended his lead to 11-5 over Stephen Maguire in their World Championship quarter-final.

The evening began brightly with breaks of 62 and 73 to get back into the game.

The world number one responded in style with runs of 64, 55, 69, 94 and 73 to reestablish his authority before the Scot took the final frame.

O'Sullivan is two frames away from a 13th Crucible semi- final.

In the evening's other last-eight match, China's Bingtao fought back superbly from 6-2 down against Mark Williams to go into Wednesday's deciding session level at 8-8.

The Masters champion engineered a five-ball plant on the way to winning the opening frame and knocked in breaks of 80, 72 and 103 to take four of the first five as the previously fluent Welshman struggled to find his rhythm after several lengthy safety exchanges.

A re-rack and a toilet break allowed Williams to draw level in the 14th frame, which lasted 50 minutes.

The match was delicately poised after Williams won a nervy final frame.

O'Sullivan storms ahead

Having been outplayed during the early session on Tuesday, Scotland's Maguire faced the unenviable position of trying to reduce a four-frame deficit against a player he last defeated in 2012 at the China Open.

At times, the former UK champion did not help himself. O' Sullivan had plenty of opportunities to pull clear, with some sloppy play and loose potting, and a poorly laid snooker attempt in the 11th frame that left him out of position, making it difficult for him to pull clear.

By that time, O'Sullivan had warmed to his task despite appearing frustrated by his cue tip.

His 94 to win the 14th frame was a wonderful exhibition of cue-ball control and spectacular potting, and he will expect to advance to the last four when play resumed on Wednesday morning.

Higgins and Trump eke out leads

The four-time world champion John Higgins was in front against Jack Lisowski at the time.

Both players struggled for rhythm and were guilty of some uncharacteristic misses.

Both of the former winners compiled two half-centuries and a century in a high-quality affair as Judd Trump leads Stuart Bingham by a large margin.

When Trump made breaks of 50 and 75 to lead 4-2, he looked like he was going to win the title, but the 2015 winner showed his resolve with a superb 106.

Trump won the eighth frame to give him a two frame advantage.
