&lt;hr /&gt;
&lt;div&gt;An abstract strategy game is a board, card or other game where gameplay is mostly without a theme and a player&#039;s decisions affect the outcome. Such games are  combinatorial, i.e. perfect information, don&#039;t involve non-deterministic elements (shuffled cards or dice rolls). This page will mostly be about two-player zero-sum games.&lt;br /&gt;
&lt;br /&gt;
Common examples of such games include:&lt;br /&gt;
&lt;br /&gt;
* Chess&lt;br /&gt;
* [[Hive]]&lt;br /&gt;
* Xiangqi (Chinese chess)&lt;br /&gt;
* Games from [[wikipedia:GIPF_Project|GIPF Project]], such as [[wikipedia:YINSH|YINSH]].&lt;br /&gt;
* Connect 4&lt;br /&gt;
&lt;br /&gt;
== Ratings ==&lt;br /&gt;
Under perfect information and the absence of luck, it makes perfect sense to quantify a player&#039;s strength or skill level with a rating system. We can assign a number to a given player, and based on two rated players, we can estimate the outcome either in a single game, or an entire match consisting of a series of games. There are different rating systems to achieve this, each with their strengths and weaknesses. The first ever rating system was Elo, which FIDE uses a modified version of. Statistician [https://www.glicko.net/index.html Mark Glickman] improved upon Elo, devising [https://www.glicko.net/glicko.html Glicko and Glicko-2], which are used by popular chess websites Chesscom and Lichess respectively.  &lt;br /&gt;
&lt;br /&gt;
A popular formula to estimate a game or match outcome, from the original Elo system, is as follows: &lt;br /&gt;
&lt;br /&gt;
Given 2 ratings &amp;lt;math&amp;gt;R_A&amp;lt;/math&amp;gt; and &amp;lt;math&amp;gt;R_B&amp;lt;/math&amp;gt;, where &amp;lt;math&amp;gt;R_A \leq R_B&amp;lt;/math&amp;gt;, we can estimate the &amp;quot;expected score&amp;quot; of player A as &amp;lt;math&amp;gt;\frac{1}{1+10^{-(R_A-R_B)/400}}&amp;lt;/math&amp;gt;. Note the use of &amp;quot;expected score&amp;quot;. In games where draws do not exist, this is simply the same as winrate. However, in games like chess where it exists, expected score is equivalent to winrate + 1/2 * drawrate. Additional formulas are required to separate winrate from drawrate in that case. The negative sign in the formula can theoretically be simplified by swapping &amp;lt;math&amp;gt;R_A&amp;lt;/math&amp;gt; and &amp;lt;math&amp;gt;R_B&amp;lt;/math&amp;gt;, but it gets a bit confusing so it will kept in this form. &lt;br /&gt;
&lt;br /&gt;
No matter the rating system used, it is important to note that &amp;quot;absolute ratings&amp;quot;, such as a particular rating, have no meaning in of itself. It is only meaningful when comparing other ratings within the same system, and even the same settings (&amp;quot;relative ratings&amp;quot;). For instance, Glicko and Glicko-2 despite being similar in many ways, the ratings they each give cannot be directly compared. A regression can be done to show they potentially correlate, but finding an exact 1-to-1 mapping is impossible. &lt;br /&gt;
&lt;br /&gt;
In this vein, if we were to try to compare rating spectrums (range of lowest to highest rating) of different abstract strategy games with a common baseline - 0 Elo set to be a &amp;quot;random-mover&amp;quot;. This is loosely eqvuialent to a human who knows the rules, but does not know anything about strategy. Suppose there is a player B which is 400 Elo above this baseline, they are expected to win roughly 90.9% of the time according to the formula above. This is completely arbitrary, but for terminology purposes let us define such a gap as a &amp;quot;thrashing“, indicating player B is an entire class above the baseline level. Then, rating spectrums can be described as &amp;lt;math&amp;gt;k&amp;lt;/math&amp;gt; number of thrashings, i.e. number of 400-Elo divisions.&lt;/div&gt;</summary>

With pieces themed after bugs, it is by far one of [[User:Emily|Emily]]&#039;s favourite games to ever exist. The objective of Hive is to surround the enemy&#039;s &amp;quot;queen bee&amp;quot; piece, which can be achieved as a combination of ally or enemy pieces. &lt;br /&gt;
&lt;br /&gt;
Emily has lovingly created a crosstable of lifelong WDL records, based on automatically fetches games played on [https://hivegame.com/ HiveGame], Click [https://neongreen.github.io/cnc/hive/ here] to view it. &lt;br /&gt;
&lt;br /&gt;
== Rules ==&lt;br /&gt;
In the opening phase of the game, players place down pieces to form a playing space known as &amp;quot;hive&amp;quot;. Other pieces cannot move until queen bee is placed.&lt;br /&gt;

		<summary type="html">&lt;p&gt;Tamp: Add &amp;quot;abstract strategy games&amp;quot; page. WIP.&lt;/p&gt;
&lt;hr /&gt;
&lt;div&gt;An abstract strategy game is a board, card or other game where gameplay is mostly without a theme and a player&#039;s decisions affect the outcome. Such games are  combinatorial, i.e. perfect information, don&#039;t involve non-deterministic elements (shuffled cards or dice rolls). This page will mostly be about two-player zero-sum games.&lt;br /&gt;
&lt;br /&gt;
== Ratings ==&lt;br /&gt;
Under perfect information and the absence of luck, it makes perfect sense to quantify a player&#039;s strength or skill level with a rating system. We can assign a number to a given player, and based on two rated players, we can estimate the outcome either in a single game, or an entire match consisting of a series of games.&lt;/div&gt;</summary>
