There is some videos on youtube which explains it pretty well.
1.b3-1...b6
I have explained in other threads on this subject that back around 1977-78, I tried this as an opening repetoire. 1. b3 is playable and even a little tricky for White at times, but it is hardly more than = against a competent opponent and you cede too much central control taking two moves to get anything pressing on e5. Maybe starting with 1.Nf3 first might be a little better.
1...b6 is horrible. White starts out claiming a chunk of center and you do nothing directly against it, so he makes another move doing the same. Now you have a passive position and you are no closer to castling than on move 1. If you survive the middlegame, you're more than just lucky.
On the plus side, I learned to defend hopelessly cramped positions. When I gave it up my rating shot up hundreds of points.
I start play in white:1.b3,black:1...b6 to everything (without 1.g3)Anyone has deep knowledge about them.
Write me if you have very deep knowledge and you play often them. tunaozates@gmail.com
