I think that the first step is to do a long analysis of the alternatives.

Junior had better hardware so maybe it played b5 because it could see that the
alternatives are bad.

[D]r1b2rk1/p1qn1ppp/1ppb4/3Pp1Pn/2B1P3/2N1BN2/PPQ2P1P/2KR3R b - - 0 13

Movei likes Bb7 on p850 and not b5 but it does not like black's position.

depth=12 -0.75 c8b7 c2d2 d6b4 d5d6 c7d8 a2a3 b4c3 d2c3 b6b5 c4e2 f8e8 c3b3
depth=13 -0.71 c8b7 c2d2 d6b4 d5d6 c7d8 a2a3 b4a5 b2b4 b6b5 c4b3 a5b6 c1b1 b6e3
d2e3

I did not watch the beginning of the game to see the moves that Junior played in
0 seconds.

The question is when Did Junior got out of book.
Maybe it got out of book in lost position.
