It's a nice program for 3 bucks – Igowin Joseki Review

Thanks to the developer for providing a handy joseki reference. If you ask me, having the rough equivalent of kogo's on the iPhone is plenty enough for me. Although I agree that a lot of new features would be useful, most of them hurt study. For example, having the computer punish a mistake is pointless. You should work out the variations as though you were always playing on the side currently to move. It helps develop one's 'mu shin' or emotional dispassion for the exaggerated security of a desired position, get me? Just memorize both sides, it's hard to think of a move by itself, you really want to know all the pairings for black then white. Anytime you have a willing go buddy or even one that doesn't play at all, you got a whole $@$ load of joseki to do. 3 bucks? I'll spend it here.
