lost in space: From my point of view it is both, a loss of White due to inaccurate moves and a win of White due to good moves.
Today it is known, that 6. ♗d2 is very promising (theory). Without theory it is -out of my view - completly impssoble to calculate the implications of this move. For example: 6...♕xd4 7. Lxb4 ♕xe4+8. ♗e2 ♕xg2 9. ♗f3 ♕g6 10. ♕d6 ♘d7. Today it is well known, that White has to play 10. ♘e2 ♘a6 11. ♗a3 ♘e7 12. ♖g1 ♕f6 with initiative (Wood-Alexander, 1948
Inaccurate White moves of White are 16. ♘b5. This is only provocing a6 (in line to blacks position and b6 is no real weaknees). Better was 16. f4. 19. ♘a4, attacing the "weak" pawn b6, but this is not really a threat.
Key moves of Black to get advantage are 20... ♘ce5!! (threat was ♖xd7 and ♘xb6). This move counters these threats and establish the own threat Qc6 with dobble attack on a4 and g2
Also 21...a5 is excellen. Black starts to attack the queenside
24. Qb3 was not the best, better was 24. ♗d4 ♘c4 25. ♗xc4 ♕xc4 26. ♗xf6 ♘xf6 27. ♘xb6 ♖xa1 28. ♖xa1 ♕b5 29. ♕d4 =
24...b5! destoys the white position on the queenside and is worth a pawn.
And this is only the first part of the game.
