[K] An alternative would be 25... Q. to B's 3d; 26. P. to K's 5th, Q. to Q's sq.; 27. R. takes R., Q. takes R.; 28. Q. to B's 2d, Q. takes Q.; 29. B. takes Q., Kt. to Q's 2d, winning the K. P.
[L] Q. to Q's 3d or Q. to B's 2d could be played. The text move gives White a chance to bring his Queen effectively into play.
[M] Kt. to K's sq. would have been safer.
[N] Marshall did not expect this complaisance, and Janowsky would not have obliged him had he seen the fatal 35. Q. to R's 4th. 34... Kt. takes K. P. should have been played.
[O] Marshall risked losing the game in trying to win. His boldness was rewarded, but the verdict should be: Don't try it again.
