🔹 Leningrad 1925
🔰 The 4th USSR Championship was held in Leningrad from August 11 - September 6, 1925. With some extra incentive provided by the chance that a good finish here could procure an invitation to the great Moscow international tournament held in November/December, the following players went into battle:
🔺Efim Bogoljubov Fyodor Ivanovich Dus Chotimirsky Sergey Nikolaevich von Freymann Solomon Borisovich Gotthilf Nikolay Dmitrievich Grigoriev Alexander Ilyin-Zhenevsky Anton Antonovich Kaspersky Arvid Kubbel Nikolay Nikolaevich Kutuzov Grigory Levenfish Vladimir Nenarokov Abram Isaakovich Rabinovich Ilya Leontievich Rabinovich Peter Arsenievich Romanovsky Alexey Sergeevich Selezniev Alexander Sergeyevich Sergeiev Veniamin Sozin Boris Verlinsky Yakov S Vilner Nikolay Zubarev.
. . . . . . . . . . . . . . . . . . . . . . . . . . .
🔰 Bogoljubov successfully defended his title, but was not as dominant as in the previous year. He started well enough with 12 of 14 to take a two-point lead over Levenfish, who had started with losses in the first two rounds. However, Bogoljubov then lost to Vilner and Verlinsky in successive rounds. This allowed Levenfish to draw within a half-point, but a critical round 17 loss restored Bogoljubov's full point lead, and the champ made sure by winning his remaining games.
🔰 With more Soviet players were now more familiar with the new hypermodern theories, the general playing level was rising and the competition getting tougher. Romanovsky, a dominant figure in previous tournaments, could only tie for 6th-8th places here. Verlinsky had an adventurous result. He defeated the top three finishers while scoring 7.5 points against the other nine players in the top half of the tournament, but could only score 4.5/10 against those in the bottom half. Had the tournament been restricted to just the top ten players, he would have won by a point and a half.
✔️ The final standings and crosstable was as above👆

15.Bxe4!
Sasikiran swaps the rather passive bishop for the active enemy knight. Regarding his own knight on d2, its mission will be revealed two moves later.
15...fxe4 16.Ng6 Re8 17.f3!
White adjusts the pawn structure so that the other knight gets into play. Moreover, he clears the b1-h7 diagonal for the queen.

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.
