A few examples from the following experiment : gnubg plays a session against itself which is then analyzed with and without Jacoby rule.

In 1040 games, there were 253 cases where the best move should differ according to 2 ply analysis. Most of them are a matter of a few millipoints. In the first 81 games, there were only the 3 positions below where the difference was larger than 0.01.
