Charlton went eight points clear of the relegation zone with a 2-1 win against Portsmouth at Fratton Park tonight.
Chuks Aneke was apparently offside when he played a big part in Charlton's opener 14 minutes before half-time, leaving the home fans incensed.
Aneke saw his header saved by Pompey goalkeeper Gavin Bazunu before Washington tapped in the rebound as the hosts screamed for a free-kick.
Clark Robertson's 64th-minute own goal doubled Charlton's lead before Michael Jacobs gave Pompey hope by reducing the deficit 11 minutes from time.
Pompey had taken the game to the visitors in the opening five minutes, with debutant Denver Hume causing problems down the left flank.
George Hirst failed to capitalise on a Joe Morrell pass in the 25th minute by missing the ball completely.
