Samit Patel and Harry Gurney took three wickets each to put Nottinghamshire in command against Middlesex.
The visitors failed to add to their overnight score of 298-9, before Nick Gubbins (23) and Sam Robson (35) shared an opening stand of 51 for Middlesex.
But the hosts collapsed to 158-7 at tea, and were dismissed for 181 shortly after the interval.
Steven Mullaney (44) and Brendan Taylor (34) helped extend Nottinghamshire's lead past 200 as they closed on 101-2.
Middlesex started well as Steven Finn removed Gurney with the second ball of the day, and then saw Gubbins and Robson safely negotiate the new ball.
However, Gubbins was bowled by Gurney, and South African seamer Vernon Philander claimed his first Notts scalp by dismissing the returning Nick Compton for three.
Jake Ball got the key wicket of Robson just after lunch, and captain Adam Voges and Paul Stirling soon followed him back to the pavilion.
Spinner Patel (3-30) then struck twice in the space of three balls removing James Harris and Tom Helm, before he and Gurney (3-50) took the final two wickets after tea.
Dawid Malan was unable to bat because a suspected broken finger he suffered while fielding on the opening day.
Mullaney and Taylor appeared to be putting Notts into an unassailable lead, but their late dismissals provided Middlesex with a glimmer of hope going into the third day.
Nottinghamshire bowler Harry Gurney:
"We've got eight seamers who could all play first-team cricket tomorrow and some youngsters who would be shoe-ins at other counties.
"It's a good cricket wicket but there is something in the wicket for the bowlers and we exploited that and put ourselves in a strong position.
"It's important to get through that first hour tomorrow. Middlesex have got a strong seam attack too and the overhead conditions are always a factor at Lord's.
"If they take two or three wickets they will be right back in it. But if you'd offered us this position at the start of the day we would have taken it.
Middlesex batsman Sam Robson:
"It was a tough day for us. We fell short with the bat and a had a poor little session with the ball after tea.
"They have a good seam attack and have bowled well but if we can take three or four wickets in the morning we can give ourselves a chance if we can show some fight and bat well in our second innings."
