*igowin at 5-handicap*
Igowin, [http://www.smart-games.com/igowin.html], firstly has long history [dated unknown] but it was the first go-software Xinwen had met back in 2005.
Just few days ago, Xinwen being bored and had managed to break personal record winning 6-dan in igowin [without cheating].
Overall, igowin being part of Smart-go [present] considerably the best igo software out there for handphone. As any Go starter out there, it is encouraged to get Igowin for themselves and set 6-kyu as the target to reach.
*winning a 6-dan in igowin*
In Xinwen’s opinion, Igowin should be about 7-kyu in 19×19 standard. It is quite good in capturing race, but bad in living. Thus, its good to practice cloce combat with it.
