Rhein Energie Köln beat Telekom Baskets Bonn 81-70 to record their fourth straight Bundesliga win and move them into the top five for the first time this season.
As is often the case in the Rhein derby, there was no lack of aggression and that helped the home side to a 22-15 lead in the first quarter.
It is the season of giving, but do not expect Telekom Baskets Bonn to present any gifts to RheinEnergie Koln on Monday.
The Bundesliga rivals, separated by just 25 kilometres along the banks of the river Rhein, are also very close in the league standings.
Alba Berlin saw off Telekom Baskets Bonn 93-87 to notch their 10th win in as many Bundesliga games despite the absence of skipper Matej Mamic.
Mamic, a Croatian international, remains in intensive care following a sickening fall last weekend which doctors initially feared could leave him paralysed.
Telekom Baskets Bonn took some of the sting out of their disappointing EuroCup campaign by capping off their involvement with a 67-58 victory over BC Barons.
Bonn entered Tuesday's game without a win in five games but Milos Paravinja's basket midway through the third quarter broke a 33-33 tie and sparked a 10-2 run to put the German team in front for good.
