My DB doesn't have :w8: , so I assume it's a mistake. What's the best move for black?

Maybe you just extend along the side like if white had played your :b1: move like he was supposed to first and treat this exchange lightly cause it already kind of cramps him?

Thanks ez4u, I was only thinking of connecting directly. Do you think that with your :b3: it is a good result for black? Is there a better move?

This is a good result and is the standard explanation for why White can't descend immediately at 8 in your original diagram. Your decision to slide into the corner was good. :tmbup:
