Something that I red on Senseis:

The following are statistics for how often the given enclosure was found in professional games in an otherwise empty 10x10 corner. The database used was GoGoD2009 winter edition (with games up to december 2009). Results have been rounded to two significant decimal places:

Enclosures with a 3-4 stone:

• 5-3 Small knight's move: 19000 times
• 5-4 One point jump: 6700 times
• 6-3 Large knight's move: 4300 times
• 6-4 Two point jump: 330 times
• 3-7 Two point jump other side: 11 times

Enclosures with a 4-4 stone:

• 3-6 Small knight's move: 3100 times
• 3-7 Large knight's move: 2900 times
• 4-6 One point jump: 730 times
