PawnSac: < louispaulsen88888888: I mean we might have to go back to the 6th move to find a way for white to save the game. 6.Qb3?! Is unusual and this game might put it out of business! >
Jobava lost a previous game with the same line the year before.

I guess he didn't learn his lesson yet. In all fairness tho, engines were not that strong yet in 03 and 04.
The customary 6.d4 ran all the way thru the Stockfish 11 eval. Note that it is only -0.23 for white (dynamically equal):
41/67 17:12 1,312,290k 1,271k -0.23 d2-d4 d7-d6 Qd1-b3 Qd8-d7 d4xe5 Ba5-b6 Bc4-b5 a7-a6 Bb5-a4 Ng8-e7 O-O d6xe5 Nf3xe5 Qd7-e6 Bc1-f4 Qe6-f6 Bf4-g3 O-O Ne5xc6 Ne7xc6 Qb3-c2 Nc6-e5 Nb1-d2 Rf8-d8 Bg3xe5 Qf6xe5 Nd2-c4 Qe5-e7 Nc4xb6 c7xb6 Ba4-b3 b6-b5 Ra1-d1 Bc8-e6 Bb3-d5 Be6xd5 e4xd5 Qe7-d6 Rd1-d4 Rd8-e8 Rf1-d1 Ra8-d8 c3-c4 b5xc4 Rd4xc4
here is the eval at the same depth after 6.Qb3 note black has a +1.04 :
41/69 16:21 1,228,819k 1,252k +1.04 Qd8-e7 d2-d4 Ng8-f6 Bc1-a3 d7-d6 d4-d5 Nc6-d4 Qb3-a4+ Bc8-d7 Qa4xa5 Nd4-c2+ Ke1-d1 Nc2xa1 Nb1-d2 O-O Kd1-c1 Rf8-b8 Kc1-b1 b7-b6 Qa5-a6 Bd7-c8 Qa6-b5 a7-a6 Qb5-b2 Qe7-d7 Kb1xa1 b6-b5 Bc4-d3 a6-a5 Rh1-b1 Bc8-a6 Nf3-e1 c7-c6 d5xc6 Qd7xc6 f2-f3 Nf6-d7 g2-g3 Nd7-c5 Bd3-c2 Rb8-b7 Ba3xc5 d6xc5 c3-c4 Qc6-h6 Rb1-d1 Ra8-e8 c4xb5 Rb7xb5 Qb2-c3 Qh6xh2 Nd2-f1 Qh2-h1
and again a little deeper its worse for white:

46/59- 34:22 2,624,668k 1,273k +1.14 Qd8-e7 Bc4-b5
The bottom line is... If you're gonna play the Evans, play 6.d4
