Nicholson lost out in the first match to Jason Askew in a 5-4 defeat but bounced back from that immediately by seeing off Jarred Cole in a 5-2 victory which saw 'The Asset' hit 5/8 on his doubles en route.
The same can be said for Arron Monk who lost out to Jason Askew who took out 142 in the deciding leg to cruelly deny the former World Youth Champion the victory, also hitting four 180's and a 99.7 average.
Monk though recovered from that to see off Robert Collins 5-4 in a game which saw him down at 3-0 but he came back to win 5-4 in a deciding leg with 5/7 on the doubles as he aims to repeat his heroics of Day Three.
