There are other non losing moves like Rb8 so it seems that the test should be
simply to avoid Bd7 and not find a5
Deep Fritz says 0.72 against black after a long search for black before Bd7 and
like a5 or Rb8(the next best move with similiar score)
After Bd7 the evaluation jumps to +1 at depth 14 and continues to get up(fail
high with +1.31 at depth 15).
