All of you go players will be happy to know that SmartGo 2.1 runs great on XP Pro x64. This is my favorite go program and it is rich with features. The dev was delighted to hear that it worked well on x64. When I told him about the kind of folks we are here in the 64bit ng, he offered a deal to the folks who participate. He has set up a coupon called smartgo64 that will give you $20 off ($69 instead of $89). The link is http://www.smartgo.com/en/index.htm. Just mention smartgo64 in your communication. Here is his description. I have no connection to his enterprise but am just a big fan of this great program. "SmartGo offers a wide range of functions for Go players from 20 kyu to 6 dan. Its powerful features are easily accessible in a well designed user interface. SmartGo comes with over 37000 professional games, and provides numerous tools to benefit from that data. You can play against SmartGo, against GNU Go, or on IGS. Price: $89. Free 15-day trial."
