The loss of Court/Hercules was a major factor coupled with the form of visiting striker Sammy Winston who gave the Ducks makeshift backline a torrid time. Gary Crawshaw slotted just wide after only five minutes, but a minute later Chesham took the lead with their first attack.
Kieran Adams centred a dangerous ball across the face of the goal and Windston tucked it comfortably past Richard Wilmot from eight yards. Prior to the break Winston twice went close but it was Aylesbury who created the better chances.
A long effort by Jermaine Darlington hit the crossbar, ballooned up into the air and bounced down onto the bar again before going over. Ian King struck a free kick just wide, and keeper Kenny Addai failed to deal with a Kieran Gallagher cross only for Jason Soloman to blast the ball over with an open goal at his mercy.
A minute into the second half Aylesbury gifted Chesham a second. Wilmot came out for an Allan Pluckrose corner, was unable to hold, and Winston turned the ball in. Despite trailing 0-2, it seemed that if Aylesbury could pull a goal back then they could still get something out of the game.
But on 56 minutes Youness Nabil crossed from the byline and, as Lee Harvey and Mark Rooney challenged Winston, the Chesham striker went down. Referee Mr Green awarded a penalty and John Lawford duly converted the spot-kick.
Moments later Lawford almost made it four with a curling 20 yard shot which hit the bar. On 65 minutes Chesham were fortunate to retain eleven on the field. Addai, booked earlier, brought down Ian Rutherford for a penalty and most of the crowd expected Addai to get a second yellow card. But he escaped without a word of caution and then saved Crawshaw's penalty.
Harvey and Crawshaw both went close to a consolation as little went right for Aylesbury on the day. Chesham deserved the win but not necessarily by a three goal margin.
