What is the difference?
Both bxc6 and Rxc6 are losing moves.

The reason not to play bxc6 in the first seconds from the point of view of chess
programs is clear.
The white b pawn after bxc6 is a passed pawn and programs give bonus for past
pawns.

There are chess programs that can see a clear advantage for white in the

I do not see a proof that computers have problem in this position.
