CARL Holmes' 50th goal for Lynn was an early Christmas cracker as the Linnets made it five wins in a row.
The Walks outfit did their first double of the season, and in just four weeks they have gone from bottom to tenth.
In his 119th Linnets game, Holmes fired in a Steven Gerrrard-like strike, a low right foot screamer from 25 yards in the 61st minute after playing a one-two with Danny Bloomfield (who has scored in the last eight matches), while David Staff marked the final game of his two-month loan spell with a goal.
On Saturday's win and only Lynn's fifth clean sheet of the season, Linnets boss Tommy Taylor said: "We didn't play very well, but we won the game.
"We can still do a lot better. When we pass the ball we look a good team, but when we work as a team we look an even better one."
Taylor handed under-fire midfielder Mark Angel the captain's armband, and said: "I wanted to put a bit more responsibility on Mark because Gary Setchell wasn't playing.
"He did brilliantly for the first goal, but still needs to work a little bit harder when he hasn't got the ball."
David Chick came in for Gary Setchell (suspended for one game). The first female referee to officiate a Lynn game, Alison Chapman, had to go off injured and was replaced by assistant ref Mr A. Groves in the second half.
The highlight of an extremely quiet first half was in the 11th minute when Staff ran from halfway, fed out wide Bloomfield, whose hard and low centre Mark Angel sent
goalwards, but Nathan Bowderi-Haase cleared off the line.
Home keeper Jamie Jackson saved with his legs from Jack Defty, feeling the effects of a training knock.
A minute before half-time an excellent four-man move saw Lynn go ahead. Mark Camm fed Angel who interchanged passes with Bloomfield and crossed for Staff to head against the bar, but Bloomfield headed in the rebound.
Bloomfield is now level with the league's joint leading scorer John Lawford, whose tally for the Generals is 123 goals in 198 games, but who only mustered a couple of soft shots before being substituted on the hour.
After Holmes' effort, Staff made it safe in the 68th minute after dispossessing a red-faced Jackson and rolling the ball from outside the box into an empty net.
Chesham were innocuous and Lynn stopper Steve Wilson was only tested late on when he dived to his right to deny sub Dave Fotheringham.
