Take flight with the Pterodactyl

One of my favorite  openings is the Pterodactyl and related systems.  Black opens with g6, Bg7, c5 and Qa5. The early queen deployment is the characteristic of the Pterodactyl.  In this article I will start out by presenting the countermeasures that are recommended by various authors and hope to show that in each case black has a playable position.  I have been very successful with this opening and will give examples in further articles.

Please remember to show the move list to show the variations.
