Which two professional games are most similar?

In other words, which two diverged at the latest move number?

Yi Ch'ang-ho vs Cho Hun-hyeon, 1995-02-08 &

Yi Ch'ang-ho vs Cho Hun-hyeon, 1995-10-02

Position at move 38  

The examples given so far have at least one pro in common. While studying the Kobayashi Fuseki, I stumbled upon an example where two 7d amateurs repeat the first 38 moves of a pro game:

Weon Seong-chin vs. Chen Yaoye (8th Samsung Cup Qualifying Preliminary, 2003-08-04)

Lee Kangwook 7d vs. Fu Li 7d (25th World Amateur Go Championship, 2004-06-10)

The pro played at , the amateur played at a. (White won both games by a small margin.)

This really makes me wonder whether common fuseki such as the Kobayashi Fuseki are too orthodox for my taste. That can be a good thing or a bad thing. Calvin
