The Chairboys kicked off their Wonder of Wycombe series with three points, as Garath McCleary's brace cancelled out a solitary Charlton goal in stoppage.
It was an even start at Adams Park, with neither team able to stamp their mark on the game in the first five minutes.
There looked to be an early opportunity as Joe Jacobson was fouled on the left-hand side and was able to whip in a free-kick deep into the Charlton box. Despite a towering Ryan Tafazolli header at the back post, the away side were able to clear.
Charlton were awarded a similar opportunity moments later, as a delivery from the right-hand side sailed over nearly all quartered blue shirts, to finally be cleared by Jordan Obita.
Garath McCleary looked particularly dangerous down the left-hand side, running his player ragged, and delivering a number of balls into the right areas.
Wycombe went agonisingly close in the 21st minute, as some quick play around the back of the box saw Curtis Thompson able to thump an effort goalward, which ricocheted off the post and away.
This chance encouraged the Chairboys, who began to take control in the opposition half as the first 45 wore on. It wasn’t long before that control paid off, as McCleary found himself able to flick the ball past his player on the edge of the box and unleash an effort which nestled in the bottom corner.
Half time: Wycombe 1-0 Charlton.
The second half started with much the same. Wycombe coming out of the blocks just as strongly as they finished the first.
In the 53rd minute, some great link up play between Josh Scowen, Garath McCleary and Daryl Horgan saw the Irishman able to unleash a shot from a tight angle, which was charged down by the Charlton right-back.
Charlton settled into the game to some extent, and although the Chairboys did create more opportunities, they came with less frequency. Another Jacobson delivery caused issues for the away defence, but was eventually shepherded out for a goal kick.
It was McCleary who made one of those opportunities count though, as a well-weighted cross was nodded back across goal and into the net in the 70th minute.
Wycombe 2-0 Charlton.
Gareth Ainsworth made some changes, adding some fresh legs in the form of Adebayo Akinfenwa and Sullay Kaikai, while Sam Vokes and goal-scorer Garath McCleary made way.
Ryan Tafazolli and birthday boy Anthony Stewart were on top form in the final 10 minutes, as Charlton threw everything at the game.
David Stockdale made an excellent instinct save at close range to keep things level in the 88th minute but was beaten shortly after as Sam Lavelle rose high to slam home a header from a corner.
Wycombe 2-1 Charlton.
A nervy five minutes of added time ensued, with Charlton continuing to push high up the pitch in search of that all-important leveller. However, the Chairboys were able to hold firm, and despite some frayed tempers as the game drew to a close, the home side took all three points.
Full time: Wycombe 2-1 Charlton.
