Welshman Williams currently sits in third position in the league and a win tonight would see him leapfrog Ronnie O'Sullivan and fellow countryman Matthew Stevens into first.
He faces former world finalist Ali Carter in the week's opening semi-final; Carter made a promising start to his campaign in week four, reaching the final, only to lose 3-1 to Ronnie O'Sullivan.
Williams was disappointing in his defeat to Judd Trump last week, but will be keen to return to the form that saw him take victory in week two.
Both players have struggled for form on the tour this season; despite reaching the final of the Shanghai Masters, Williams has suffered a slump on the PTC tour, tumbling down to below 100 with only two wins.
Like the former world number one, Carter has been inconsistent so far, losing in the first round of both TV ranking events.
They are both renowned for their high break-building ability, which should make for a close game.
The bookmakers favour a Williams victory however, offering 8/13 on the Welsh potting machine, with Carter good value at 6/5 with Bet365.
The match begins at 7.30pm and will be streamed live over the best of five frames under the 20 second shot clock rule.
