KEG: A surprisingly tame effort by Lasker, who avoided sharp lines in the opening, missed a chance for a significant advantage on move 17, and then allowed Cohn to reduce to a drawn position.Lasker had won an impressive game against Lee in the third round of this tournament against the (then) new 4...Bf5 line in the Caro-Kann Defense. But here, Lasker ignored two opportunities to try to seize the initiative with either 7. h4 or 8. h4 and instead played the placid 7. Be2 and 8. c4.
The game was about even before Cohn's weak 15...Nh7 (15...e5 was best) and 16...Ndf6 (instead of 16...NxB).
Lasker could have gotten much the better game with 17. NxB. But after 17. BxN and 18. d5 (18. NxB was again best), Lasker's edge was gone. Either this was a day Lasker decided to take a breather or(more likely) he missed the intermediate move 20...Bb4.
Whatever the reason, Lasker for once seemed flustered, and erred with 21. Re2 (missing the far better 21. Rc1), giving Cohn some chances, though nothing approaching a winning edge.
Cohn, probably delighted at the chance to get a draw with Lasker with the Black pieces, allowed the exchange of Rooks and a pair of minor pieces, reducing the game to a peaceful end on move 29.
Had Cohn wanted to try for a win, he could have played 27...Bf8 rather than allowing Lasker to trade off his Bishop after 27...Ne4 28. NxB QxN.
Given his big lead in the tournament, this draw probably did not cause Lasker any significant consternation.
