Last post I started to discuss the AB Adjacent corner openings. In this post I wanted to continue this discussion with a focus on the 'AB-D staccato':

[PTN: 1. a5 a1 2. b1 d2 3. d1 e1]
While it may not seem like much, white now has a number of options that can change the look and feel of the game. With black having cut off the imminent threat of the 1-row, white now has a few options. For one (I), white can put pressure on the lower d&e squares - continuing the original thread. Alternatively (II), white can aim for the center (c3) or some surrounding squares. Or (III), white can direct some attention up the b-file. There are certainly other possibilities, but these are certainly the major lines, each with a different feel and rhythm.
