iPad/iPod/iPhone user alert: In “SGFs and iStuff” (2/1/13), I looked at some issues related to viewing sgf files on iPods, iPads and other mobile Apple products. I managed to confuse some readers, so please note that I was referring specifically to apps for mobile devices, not desktop-based software. One reader disagreed at some length with my conclusion favoring Smart Go Kifu (SGK) over EasyGo, so I took a closer look at the two apps. The reader raised some specific questions: What about when you’re recording a game and realize you skipped a pair of moves? How do you place un-numbered stones when setting up a problem? I found that both apps have these functions. He also offered a link to a review from last April with information that is, in some cases, incomplete or inaccurate. SGK actually does keep problem statistics, but only for one user (EasyGo can track multiple users.) SGK only imports one file at a time, but that file can contain many games or problems; just concatenate them into one file on your desktop, using software such as the freeware Kombilo. EasyGo does offer one unique feature — a “time line” type graph that shows where the next comment will be. You can test it in the free version if you like. On the other hand, SGK’s problem collection is better. I’ve been studying a lot of problems lately. I find it is the perfect time filler when you’re waiting in line, riding the train or otherwise briefly idle. If you guess the wrong answer in EasyGo, you get a big red X that tells you to try again. SGK’s response is more thorough. Your wrong move says “1?”, and the other side’s best response appears, so you can play out failed variations and see why they don’t work. (If you don’t even get a “1?”, you know you’re not even close.) When you’re right, your stone says “1!”, but you still have to finish the variation to get credit, and if you go wrong along the way, you’ll get a “?” to let you know, and you can play it out and see why. With so many other features — a playing engine, a collection of 40,000 pro game records and a “Guess Next Move” function , to name a few — SGK still seems clearly worth the higher price. When I’m finished studying SGK’s >2000 problems, I’ll probably pick up EasyGo too, for the problem collection; or I may just get one of the classic problem books that’s available through Smart Go. Or both.
