Answers.Body: <p>From <a href="http://www6.chessclub.com/help/PGN-spec" rel="nofollow noreferrer">Portable Game Notation Specification and Implementation Guide</a>:</p>
  <blockquote>
  <h2>7: Tokens</h2>
  <p>Tokens <strong>may be</strong> separated from adjacent tokens by white space characters. (White space characters include space, newline, and tab characters.)</p>
  </blockquote>
  <blockquote>
  <p>An integer token is a sequence of one or more decimal digit
  characters.  It is a special case of the more general &quot;symbol&quot; token
  class described below. Integer tokens are used to help represent move
  number indications (see below). <strong>An integer token is terminated just
  prior to the first non-symbol character following the integer digit
  sequence.</strong></p>
  <p>A period character (&quot;.&quot;) is a token by itself.  It is used for move
  number indications (see below).  <strong>It is self terminating.</strong></p>
  </blockquote>
  <p>and</p>
  <blockquote>
  <h2>8.2.2: Movetext move number indications</h2>
  <p>A move number indication is composed of one or more adjacent digits
  (<strong>an integer token</strong>) followed by zero or more <strong>periods</strong>.  The integer
  portion of the indication gives the move number of the immediately
  following white move (if present) and also the immediately following
  black move (if present)</p>
  </blockquote>
  <p>So you see that, by spec, any spaces after move number don't matter at all.</p>

  <p>I've seen both with and without the space. On Wikipedia there are spaces. But I checked in three of my books and there isn't any space in any of them.</p>

  (Asked by: username_0 on 2014-07-02)
  
  I know everyone will say that this is a stupid question, but I'm going to ask it anyway...
  
  Is there a space between the move number and the move algebraic notation?
  
  In other words, which of these is the correct notation? :
  
  1.e4 e5 or 1. e4 e5 ?
  
  26.Nxe4 or 26. Nxe4 ?
  
  8...Bb4+ or 8... Bb4+ ?
  
  I've seen both with and without the space. On Wikipedia there are spaces. But I checked in three of my books and there isn't any space in any of them.
