RULES

For Hivers, Steemians, Blurters and all others!
Players of all skill levels are welcome, from newbies to experts, you just need a Lichess-account!
Every Friday 19 to 20 GMT is one round (with few exceptions).
Time mode is varying (5+0, 5+1, 3+2, 10+0,...), rated, berserking allowed (except in Swiss mode)
The winner of each round gets 8 points, the second 7,... and the 8^th 1 point. In case two players have the same number of points, the one who played less rounds is first. If that is equal too, then the average tournament performance decides.
PAYOUT: A season goes over 11 rounds and points are summed up. All Hivechess-related post rewards are pooled and 90% go to the price pool. The winner will get 30% of that price pool, the 2^nd 20%, the 3^rd 10%, the rest is divided among the other players active on Hive or Steem, according to the no. of rounds they have played. So everyone has a chance to get something and the more you play the more you get! Prices are payed out only in Hive Tokens.
If I don´t know your Hive (or Steem) username, I can´t consider you in the rankings, so if new here, please let me know your user name in the comments.

Please share this announcement among your (chess) friends and colleagues!
The more participate, the more fun! And maybe some are even interested to join Hive and it´s growing Chess Community?

GOOD LUCK!

In a Blitz game yesterday I had this position. The black pieces are somewhat not well placed but c4 it threatening which would create a passed pawn for Black. Is there a way for White to force a win?

White to move and win
