2828 - 48 = 2780
2654 + 61 = 2715

So it seems that Rebel12 is stronger than the one called Rebel12_CB.
The Rebel12 games are with the prerelease version and played mostly under
Winboard.
The Rebel12_CB games are with the released version and played under Arena.
But I do not know why we should see a statisically significant difference.
