  <p>After <code>3.

  <p>I think <code>...e5</code> gives white a better game than one of the usual variations.

There's also opportunity to pile up black's <code>f7</code> pawn, which is typically awkward to defend using a minor piece.  However, it's not really all that bad; it's somewhat similar to the <a href="http://en.wikipedia.org/wiki/Sicilian_Defence#Sveshnikov_Variation:_4...Nf6_5.Nc3_e5." rel="nofollow noreferrer">Sveshnikov variation of the Sicilian defence</a>.</p>
  
  <p>Comments:</p>
  
  <ul>
  <li><p>I personally like swapping off white's dark squared bishop for black's <code>f6</code> knight, then placing one of white's knights at <code>d5</code>.  Sooner of later, black will need to swap off his light squared bishop to dislodge the knight, thereby giving opposite-coloured bishops, a particularly important imbalance.  If I can't find the right attack, I can still swap off into an opposite-coloured bishop endgame, which is likely an easy draw despite being a pawn down.</p></li>
  <li><p><strong>I find black's <code>...Bg4</code> to be a very annoying move</strong>, since it pins the <code>f3</code> knight against the queen, and threatens <code>...Nd4</code>.  This seems to be the main advantage of <code>...e5</code> over <code>...e6</code>.  Keep an eye out for this move; in some cases, it can be a game-changer.  Sometimes it's helpful to take time to play <code>h3</code> to prevent this move.</p></li>

Answers.Text: +1 for "not really all that bad" and for giving "Black's best play" (Bg4). As a Morra player as White, I too have tried to refute ...e5 (because it seems the logical way to immediately shut down one of White's "best" options in the Morra, e5). My conclusion was that White cannot develop any real threats (such as after Qb3) because Black can always get in Nd4 interfering. And of course it gets White out of the normal Morra "book" she is expecting (psychological advantage).

  After 3. Nf3, I haven't announced my intention to play the gambit since it could transpose into mainline Sicilian Defence (although, black's 4...Qa5+ might commit you to it; see my recent question here).

The usual themes with backwards pawns on a half-open file apply: ganging up on black's d6 pawn and d5 hole; if the d6 pawn is pinned, the e5 pawn is also weak.  There's also opportunity to pile up black's f7 pawn, which is typically awkward to defend using a minor piece.
