Kombilo is a go database program. Its main purpose is to search for games in which a given pattern or position occurs. You can also search for other criteria (like time period, players, events). This program does not come with any game records, but you can import games in SGF format, so for example you can use one of the game collections which are freely available for download. The GoGod database by John Fairbairn and T Mark Hall (+ 2013) is also an excellent choice.
