26. Qc7?
It is always nice to have one's Queen posted on the 7th rank. But the text was a mistake and created needless problems for von Scheve. He would have been fine with the simple 26. Qxf5, despite the (at first glance) frightening check on f2: e.g., 26. Qxf5 Rf8 27. Qe5 Rxf2+ 28. Kg1 After 26. Qc7, the position was:

The Tournament Book correctly noted that 26...Qxa2? would have been a mistake, but its further analysis of the move was preposterous. Had White responded 27. Ra1 as suggested in the Tournament Book, he would have converted a strong position into a losing one, since Black would simply play 27...Qxb2. If White then followed up with 28. Rxa7?? as the Tournament Book further suggests (28. RxN was probably White's only chance), Black would win instantly with 28...Qxf2+ 29. Kh1 Rd7! After 26...Qxa2?, White could get an excellent (though nowhere near winning) game with 27. Ne3. In any case, after 26...Qa4, the position was:

This should have lost straight-away. By contrast, von Scheve could likely have weathered the storm with 27. b3 or 27. Rbd1. After 27. Re2?, however, Teichmann could have won by exploiting the position of the White Queen on c7, the board now showing:  click for larger viewTeichmann must have also been in time trouble, else he would surely have found the crushing 27...Rd7! The game would likely have then continued 28. b3 (forced) Qb5 29. c4 (forced) dxc4 30. a4 (forced) RxQ [30...cxb3 also wins and transposes to the main line] 31. axQ cxb3 32. Rxb3 (forced) c4 and wins. But, instead, Teichmann played:
27... Qb5?

The suggestion of <zydeco> of 28. Rc2 is also bad: 28...Rc8 [28...Rd7 also wins] 29. Qxa7 [everything else is even worse] Qc6! (dooming the White Queen] 30. f3 Ra8 Now, after 28. c4? Teichmann had a likely win with 28...Qxc4. But he gave von Scheve a chance with: 28... dxc4?
Now, 29. Rbe1 might have allowed von Scheve to survive. But instead he played: 29. a4?
Now, Teichmann was again in the driver's seat:
29... Qxa4
