Factions
Pick a side
Three factions, one map. Whichever you join, the other two want your street.
Rooks
Straight at it. No detours.
Knights
Move in unexpected ways.
Bishops
Halfway across the board already.
The map
40,000+ monuments in the Netherlands. Most are still uncaptured.
Bridges, windmills, church towers, statues, parks, artworks, pumping stations, viewpoints and public chess boards, from Wikidata and OpenStreetMap. Every one of them can be yours by tonight.

Five kinds of chess challenge

Tactic
Find the winning tactic.

Finish this game.
Endgame technique
Win from this position against Stockfish.
Openings, tactics, mates and endgames are rated separately. Difficulty follows your own rating, so a beginner and a club player both sweat a little.
Your map too
Put your club or chess board on the map
Clubs, outdoor boards, and anything the map missed
Does your club play at a fixed venue? Is there a chess table in your park that the map does not know about? Send it in. A person checks it, and it becomes a monument every player in town can walk to.
Add a monumentKeep your head up out there
This game sends you into the real world. Look around you rather than at your screen, play the challenge standing still, and do not go anywhere you are not supposed to be.
