I usually get into this position, where I just recently moved the bishop to g5 (or b5), and his response is moving h6 (or a6):
Usually here, I only consider two possibilities:
- Take the knight
- Retreat my bishop*
- Do anything else (rarely profitable)
* either to h4 (or a4), or back in the long diagonal where it came from
I know this position strongly depends on how the other pieces are in the board, but I am sure there are standard responses, with their pros and cons.
I would like to study this position in-depth, possibly read some books that talk about it, anyone can point me in the right direction?
Also, in case of moving it to h4 (or a4), is it considered a mistake for black to attack again moving the other pawn two squares?
