I believe it is "well known" among amateurs that there are no particularly effective follow-up moves in the corner after one starts with a play at hoshi. This is what most joseki books tell us. Nevertheless playing a small knight or large knight extension from a hoshi stone seems to be becoming somewhat popular in recent professional play. I wanted to investigate whether this has led to favorable results. As usual I turned to GoGoD CD and Kombilo. The results were very surprising! I looked at the period 1990 to date (July 2002) and compared three choices: Playing a small knight's move enclosure
(Actually this is a small lie, there were 55 cases of making the shimari by starting with the 5-3 point :-)

Playing a large knight's extension from a hoshi stone

The number of games involved did not provide a very high degree of precision. However, the results are certainly suggestive. Have you tried this in your own games lately? --DaveSigaty adamzero: In my own games, I've noticed that the small knights extension off the 4-4 works particularly nicely. I like to play fairly profit-oriented game, making strong groups from which I can attack or invade without fear. Often my opponent builds moyo that I have to invade, but because this happens so frequently invading has become one of the better parts of my game. The small knights extension off the hoshi works well for me because it threatens to grab very large profit, inviting my opponent to challenge, and I can then attack strongly. I particularly like playing it when it leaves the open side of the hoshi stone facing my own thickness. I've had good results with this. I don't like the large knights extension because it seems to invite the san-san invasion too strongly, and I'm rarely satisfied with the result. And when I'm playing against it I immediately start trying to figure out the appropriate timing for the san-san invasion, and having played it I am usually pleased with my gains.
