[D]r3rk2/1p6/2p3P1/4nP1p/pP2p3/P1B1NbPB/2P5/5RK1 w - - 0 1

Deeeper blue planned to go to this position in move 37 but did not do it

at depth 7(6) after 3 seconds it planned to play Rd8-a8 in order to get this
position with evaluation of -24

Rd8-a8 failed low at depth 8(6) and deeper blue got evaluation of -54

Deeper blue solved the fail low problem with evaluation of -98 and changed its
mind to another move b5 with clearly better evaluation.

It is interesting to compare evaluation of programs after b5(the move that was
played) and after Rd8-a8 the move that was not played to see if Deeper blue had
a good reason to fail low.
