A Friendly Game of Chess is a Tavern Brawl. It debuted on October 5, 2016.

Based on the One Night in KarazhanBlack King encounter from One Night in Karazhan, all matches in the Brawl are played on the Karazhan battlefield.

This Brawl sees players recreating the One Night in KarazhanBlack King encounter from One Night in Karazhan. At the start of each Brawl the players are randomly assigned to play either the White or Black King heroes, each with only 10 Health. Both use identical premade decks of 15 special cards, as well as the Castle Hero Power, matching the encounter's Heroic mode version. With most minions unable to attack directly - instead dealing damage automatically - players will have to think carefully in order to triumph in this Brawl.

  • With the exception of the One Night in KarazhanWhite Knight and One Night in KarazhanBlack Knight, the pieces in this fight do not attack as normal. Rather, they Auto-Attack at the end of the owner's turn against the opponent's minions across from them.
    • If both players have an uneven number of pieces on the board, Auto-Attack minions except those on the edges will attack both minions across from them.
    • If an Auto-Attack minion has no minions directly or diagonally across from it, it will deal damage to the enemy hero.
    • As with all end-of-turn effects, minions which have taken fatal damage will not be removed until all pieces have completed their auto-attacks.
    • Despite the ability's name, One Night in KarazhanWhite Bishop/One Night in KarazhanBlack Bishop do not attack at all, but instead restore Health. They do not follow the usual Auto-Attack rules for targeting, instead healing minions to their immediate left and right.
  • Unlike other Hero Powers Castle can be used as many times as the player likes, as long as they have the mana to spare.


"Proper positioning is key to victory. Get those double attacks!" - One Night in KarazhanMoroes

The small deck size in this Brawl is matched by the heroes' low Health, making for short but strategically intense matches. Be aware of your limited card pool and try to outlast the opponent through good use of the Bishops, and cunning positioning to eliminate of the opponent's pieces, especially the Queens, as well as the other special pieces.

Adding 2 or more pieces beyond the opponent's current board size can allow you to sneak in some damage directly to the enemy hero, but focusing on getting in those "double attacks" usually yields better results. Try to maximise diagonals and focus hard on damaged and high priority targets.

The Hero Power can be very useful for focusing fire and redistributing healing - ideally bear it in mind when summoning minions. It can be used repeatedly, allowing for complex repositioning, which is particularly useful in the later rounds as the deck and hand empty.


Both heroes' emotes match those from the original One Night in KarazhanBlack King encounter.

White King
Type Emote
Thanks How very kind.
Well played Checkmate.
Greetings Care for a game?
Wow Ah, exceptional.
Oops Oh, a blunder.
Threaten I see a mate in 4.
Concede Checkmate...
Opening remark En garde!
Thinking [1] Rook to A3...
Thinking [2] Knight to F6...
Thinking [3] Queen to E5... No, no...
Black King

Due to his original role as the enemy boss, many of the Black King's emotes are written as if in direct response to the matching emotes of the White King. The Black King also lacks Thinking and Concede emotes, for the same reason.

Type Emote
Thanks Any time.
Well played Not yet.
Greetings Always.
Wow Naturally.
Oops Or a trap?
Threaten I see one in 3.
Concede <No emote>
Opening remark None shall pass!
