15.f4!
A powerful thrust that creates new opportunities on the kingside. White now threatens f5-f6 in order to soften up the f6-square, while e4-e5, seizing the centre, might also come into consideration.
15...f6?
Preventing the f5-f6 plan once and for all, at the cost of weakening the light squares and restricting the bishop on e7. However, the alternatives all lead to trouble for Black:
16.Kh1
A prophylactic measure in conjunction to my next move, which will expose the g1-a7 diagonal.
16...Nc5
Finally the knight reaches its destiny. 16...Bd8, intending ...Bb6, fails to 17.b4! forcing the queen to retreat.
17.Bxc5!
It might appear illogical to swap the "good" bishop, but this exchange has several virtues. White gets rid of the opponent's most active piece, the knight on c5. Moreover, after ...f7-f6 has been played, the d4-square is in fact more useful to a knight, where it can access the weaknesses on c6, e6 and f5. Finally, if we imagine a later exchange of the light-squared bishops, as well as of a pair of knights, then White would reach a "good knight vs. bad bishop" scenario. We already came across this topic in the Sasikiran-Iljushin fragment.
17...Rxc5 18.Nf3 Qb6 19.Nd4+/-
White now enjoys a pleasant edge thanks to his light square control. In retrospect, please note that he would probably not have reached such a favourable situation without playing 15 f4, whose tactical potential (cf. the 15...Nc5 subline) convinced Black to weaken his structure by 15...f6. Again, tactics at the service of strategy.

☑️ Berlin Grandmasters (1918)
In 1918, toward the end of the Great War, Bernhard Kagan organized several chess events in the city of Berlin, Germany. Among these events was a Großmeister-Turnier held in the Kerkau-Palast from September 28th to October 11th. Four famous, top players participated in the double round robin tournament, including the world champion Emanuel Lasker, former world crown challenger Dr. Siegbert Tarrasch, potential world challenger Akiba Rubinstein, and former world crown challenger Carl Schlechter. Lasker had managed well during the course of the war and was in fine shape for the event. Rubinstein had journeyed to Berlin earlier in the spring and had improved his form over the year. As to the other players, Dr. Tarrasch had suffered tragedies, losing three of his sons to the war, and Schlechter arrived for the event obviously sick and malnourished. These facts can be said to outline the course of the tournament, with Lasker triumphing and both he and Rubinstein going undefeated, while Schlechter and Tarrasch had terrible results, especially in the second half, each losing to Lasker. Lasker was awarded the grand prize of 1200 marks for his win, while the remaining prize purse was divided among the final three with Rubinstein being awarded 1000 marks, Schlechter 900 marks, and Tarrasch 700 marks. The final tragedy of the tournament was that it proved to be Schlechter's last elite competition with the best in the world. The great gentleman chess master, who had been the only challenger ever to draw Lasker in a match, died two months later on December 27th, 1918.
The final standings and crosstable:
1 Lasker ½½ ½1 11 4½
2 Rubinstein ½½ 1½ ½1 4
3 Schlechter ½0 0½ ½½ 2
4 Tarrasch 00 ½0 ½½ 1½
