At Obvius, tennis is the most important. We have trainingsessions every week but in addition, there is a lot more. We also organise tournaments, clinics and competitions.

Every week there are sessions at every level. The sessions are on Monday and Tuesday evening. Every member that enrolled for the sessions has 1 session per week during the whole year. More information about the trainingsessions can be found here.

D.S.T.V. Obvius participates every year in the fall and spring competition from the KNLTB. There are teams at every level. More information about the competitions can be found here. 

The beastmode is a tennisclinic from a famous tennisplayer (mostly from the Netherlands). He or she will give a clinic about a specific part of the tennisplay. Usually, there are four beastmodes per year. 

During the year we also organize an unoffical internal competition. This is orginised with the use of the app 'KNLTB Match' in which you can plan your own games with your opponent.

Club championship
The club championship is held once per year. On the side of the tennis, there are also other activities like a pubquiz. More information about the club championship can be found here.

Open tournament
The open tournament is the official tournament organised by Obvius. Players from other tennis associations can join this tournament as well. Also during this tournament, there are other activities going on. More information about the open tournament can be found here.

Delftse Derby
During the Delftse Derby, members from Obvius battle against members from Tenniphil, our tennis sister from Delft. The Derby is organised over four Wednesdays during the end of the year. 

Competition exchange
To prepare for the spring competition, a tournament for one day is organised together with Qravel, our tennis sister from Leiden.

Play in your free time
If you are in possession of a X membership, you can always decide to reserve a court and play for free. This will not cost you any extra money.
