KEG: Post II
After Marshall's 8...f6?, the position was:

Rosenthal in the Tournament Book claimed that 9. Bf7+ was better, but after 9...Kd8 10. BxN fxN 11. d3 h6 12. Be3 Nd4 (better than Rosenthal's 12...Bb4) White's advantage is minimal, whereas Mieses' actual move should have brought him victory. 9... Na5
10. NxR
Another option discussed by Rosenthal was 10. Bd5 c6 11. NxR cxB 12. Nxd5 (but 12. Nb5 or 12. exd5 were better and give White a likely winning advantage). 10... NxB

It is doubtful if Marshall could have survived here with best play by Mieses. But the game is already complicated--and gets more so very soon--so anyone calling this a clear win for White in over-the-board play would be misguided. 11. d3 Nb6
11...Bb4?! is the sort of move I would have expected from Marshall here. It messes up White's pawn structure and allows him to win the h8 Knight fairly quickly. If Marshall chose to avoid the maniacal line after 11...Bb4?!, I would have expected him to try 11...Nd6. Now, with best play, Mieses would seem to be able to get Marshall on the ropes. But... 12. g4?!
A wild coffee-house attacking move by Mieses. However, and as Rosenthal pointed out in his commentary, 12. Nb5 was far better. The text gives Marshall chances, and he leaps at the chance. 12... Nf4!
All of a sudden, Marshall is back in the game. He may still be theoretically lost, but now Mieses needs to watch his back. 13. BxN exB

In his zeal for a King-side attack and rescue of his h8 Knight, Mieses misses his final chance to preserve his winning chances. As Rosenthal correctly pointed out, 14. Nb5! was best here. 14... Bb4
It is wonderful to see how Marshall begins to turn around the game from this point. Also good was 14...d5. 15. h5?
Still pursuing a bad plan. Mieses would still have had play to save his h8 Knight with 15. g5. As is obvious, the game is slipping away from Mieses. 15... Kf8
Going after the Knight before Mieses' troops can rescue it. 15...d5 was another strong move. 16. 0-0-0

Wrong plan for Black. Marshall should have played either 16...d5 or 16...Kg8. 17. bxB d6

 click for larger viewFrom here, Mieses' game went steadily downhill. In the above-diagrammed position, he was certainly not worse. But this was the last time in the game that would be true. As will be covered in my next post on this game, Mieses' play collapsed from this point on, and he was lost within a move or two and Marshall thereafter raced on to victory--and one step closer to 2nd place behind Lasker (a prize he lost when he was defeated by Maroczy in the final round). |
