These puzzles are all taken from the Lichess Bundesliga, a massive league with more than 5,000 players and hundreds of teams. The league has promotion and relegation and players of all levels can find a reasonable challenge.
If you are interested in forming a team, and can guarantee the participation of at least 4 players, or if you have any questions about the League, please send a PM to League organizer FM Jens Hirneise: https://lichess.org/inbox/jeffforever
This first position is from Carlseng - IM Bala Chandra Prasad in the top league. White is crashing through on the kingside but it's black's turn and he can win with accurate play.
Black to play and win. Please hit the heart button if you liked the study!
