Nuno Espirito Santo's runaway leader will have the chance to go 12 points clear when it hosts Brentford on Wednesday (AEDT), after 2018 began in the perfect fashion.
Cardiff City had run Wolves closest in the first half of the season, but Neil Warnock's men have now lost four in a row, after going down 2-1 at Queens Park Rangers - Matt Smith and debutant Paul Smyth striking after Joe Ralls had put the Bluebirds ahead from the penalty spot.
Derby is two points clear of Cardiff in second after drawing 1-1 with Sheffield United in a game which saw the Championship's leading scorers Matej Vydra and Leon Clarke find the net.
Bristol City could have leapfrogged the Rams, but ended up falling a place after its goal difference took a hammering at Aston Villa, which ran out 5-0 winners. Robert Snodgrass scored twice, with Scott Hogan, Birkir Bjarnason and Conor Hourihane also on target.
Burton Albion remains in the bottom three, despite an incredible 3-0 win at managerless Sheffield Wednesday.
The battle at the bottom is becoming ever-more fraught after Monday saw more teams dragged in, while Tony Pulis picked up his first win as Middlesbrough boss.
