In the 4th season of the Rapid battle, the group stage has ended and the elimination stage has started. Players will have to play a best of 4 games with 15+10 time control to qualify each time. In case of a draw there will be extra games to decide the winner. For more information about the Rapid battle and to stay tuned about it join the #rapid-battle channel.

In the crazyhouse league, teams will be formed this week and even if you register now, there is a small chance that you will also be on a team. For more information join the #crazyhouse channel. Also @okei made a blog recap of season 3 of the crazyhouse league. Click here to view it.

The March simul will be hosted by @SomethingPretentious on Saturday March 16th @ 15:30 UTC! There may be rating restrictions. If you’re too high rated but have a blindfold account that is below the restriction then you can play! So if you want to play blindfold with a blindfold account maybe start working on getting yourself a classical rating. There is also a prediction contest in #4545-simul to see who will predict most accurate the performance of @Somethingpretentious in this simultaneous exhibition.

Study

@alms made a study about his games in the 13th season of LoneWolf. For those that learn german, it is a good chance to test their reading skills and understanding the analysis.
