Emergo - quintessential column checkers

Submitted by christian freeling on Monday, 29 December 2008
Hello all, it's almost year's end and I wish everyone here a very happy 2009. I want to thank Richard in particular for a great site, and for implementing Havannah. Now my friend Ed van Zon and I have another suggestion: Emergo.
Just to tentatively probe the idea, I've published the about down here:


We I did not invent Emergo, we discovered it.

Quintessential
Quintessential games lead a basic principle of placement and capture to its logical conclusion - one can only follow and see where it leads, whether illustrious like Go or modest like Checkers. Emergo is the quintessential implementation of a mechanism of movement and capture called 'column checkers'. Its name is derived from the Latin 'Luctor et Emergo', the motto of the Dutch province of Zeeland, and meaning 'I wrestle and emerge'.
Its origin is a really bad game called Bashne, invented some two centuries ago in Russia. The great Emanuel Lasker improved on it with his game Lasca. But Lasker made a classic mistake: he left a great idea where he found it. It has affected the game's reputation in a negative way.
To the lobbyists Lasca was 'obviously superior to Checkers' - they ignored its contamination. To the skeptics it was too erratic to be taken seriously - they ignored it altogether. As a result the potential of the concept has been grossly neglected.
Column checkers - for dire want of a better name - suffers from a 'weird checkers' image. As it turns out, Emergo is so wide that Chess, Draughts and Go simultaneously drown in it in terms of the number of possible positions. Yet it has less material than any of them. Its inner logic is as flawless as one would expect. Its strategy is basically simple but its tactics are fabulous, both in variety and depth.
However, the small player base for 3-dimensional games doesn't work in its favor.

The game is a joint effort with Ed van Zon, who got me interested in Lasca's way of capture in the first place.
A hexagonal variant, eventually turned out to be intrinsically flawed, ironically due to the very properties that make the square version such a great game. It is featured in R. Wayne Schmittberger's 'New Rules for Classic Games' (John Wiley & Sons, Inc. New York - ISBN 0-471-53621-0) and in Games Magazine (February 1986).


Of course Emergo can be played at MindSports, as indeed Havannah and many other games - we noticed however how much more 'player friendly' Little Golem has been styled. This, as much as the game's initial 'treshold', may have caused the relatively small player base. Havannah for instance is played rather massively here too, compared to MindSports :)

Cheers,

Havannah on Little Golem

Submitted by Richard Malaschitz on Saturday, 01 November 2008
With permission of Christian Freeling I implement Havannah on Little Golem. Havannah was invented by Christian Freeling in 80'. In 1981 and 1982 game gained Spiel des Jahres Recommendation.

Rules

Havannah belongs to the family of connection games as TwixtPP or Hex. Game is played on hex board with 8 cells per side. Bigger or smaller boards are possible too and game is often played on board with 10 cells per side.
  • Each player places one stone of their color on the board per turn.
  • Stones are never moved, captured, or otherwise changed.
  • A player wins when they complete one of three different structures from unbroken lines, or paths, of connected stones, all of their color:
    • A ring is a loop around one or more cells (no matter whether the encircled cells are occupied or empty).
    • A bridge, which connects any two of the six corner cells of the board.
    • A fork, which connects any three edges of the board. Corner points are not considered parts of an edge.

Links

  • Mindsport - this is best page about Havannah. There are articles with basic tactic, strategy and two example games.
  • BoardGameGeek - On BoardGameGeek has Havannah average rating 7.05 (more than Hex, Twixt, Four in Row or Gomoku)
  • Wikipedia - short article on Wikipedia.

Implementation on Little Golem

Implemented version is with 8 cells per side. I am planning implement all sizes between 4 and 10 cells per side soon. iPhone version is implemented too.


Little Golem News: iPhone support

Submitted by Richard Malaschitz on Tuesday, 21 October 2008
Since I am iPhone owner I usually play Little Golem games on this one. Because it was not very comfortable, I made special iphone pages for it and I change size of graphics in several games. iPhone users can type address www.littlegolem.net and they are redirected to www.littlegolem.net/iphone. There are some screenshots from iPhone:

Chess Tactics from top LG players

Submitted by Richard Malaschitz on Monday, 20 October 2008
In blog posts (and forum) is new easy way as include tournament table or game position.

You can write [game;id:123456] or [game;id:123456;move:20] or [game;id:123456;move:20;title:some text]. For tournament table you can write [tournament;id:chess.ch.10.2.1].

I choose some tactic positions from last finished chess championship. Tournament was very close:
