Once more:
Back around 1978 or so, I thought it would be really a simple (lazy) way to prepare a repetoire by playing 1. b3 and 1...b6 against anything. 1.b3 is OK (actually it seemed better as 1.Nf3 2.b3) but 1...b6 really sucked something awful. After two moves, you don't have any King-side development and you really aren't threatening anything that can't be defended. After a year or so of defending cramped, lifeless positions, I gave up and went back to open games with great results. The one thing I learned from it was how to defend horrible positions, so I guess it wasn't an entire waste. But generally, avoid 1...b6.
B3 for white and B6 for black. Are these good or bad openings and why?
I personally love these openings and feel they can be used against everything. However, ive read many conflictiing opinions about these two openinngs.
