Continuing with examples from the games of grandmaster Efim Bogoljubov…

gm Alekhine,A
gm Bogoljubov,E
Rastatt 1914. Position before Black’s 37th move. A sharp game with both Kings feeling insecure. In such positions two things are of utmost importance: the initiative and having the move!
BLACK TO PLAY AND WIN!

Rabinovich Ilya
gm Bogoljubov,E
Triberg 1915 Position after 20 moves. A neat tactic with a geometric theme. Black seems quite ok (the Bishop pair vs isolated queen pawn is a common occurrence in modern openings) but the Black Rook is on the wrong square…
WHITE TO PLAY AND WIN!

gm Reti,Richard
Berlin 1934. Position before Black’s 34th move. Black has an obvious advantage, both materially and positionally. But Queen and Rook endings are notoriously difficult. Here, however, the White King is a bit exposed and this gives Black an idea……can you also find a way to end the game quickly?
BLACK TO PLAY AND WIN!

gm Rubinstein, A
gm Bogoljubov,E
Stockholm 1919 Position after 33 moves. White was getting crushed earlier, but Black suddenly went astray and played a bit superficially. Rubinstein is counting on the threatened check on g2, but Bogoljubov finds a surprising refutation to Black’s attack! (Note: 34.Rxf3?! Qxe1! is just unclear)
WHITE TO PLAY AND WIN!

gm Bogoljubov,E
gm Rubinstein,A
Stockholm/Goteborg match 1920 Position after 21 moves of play. White had sacrificed a pawn for the initiative, but seems to have hit a dead end. The Black King seems very well protected (the check on h7 is harmless) and is about to expulse the White Queen with …Nf8. However, the great Rubinstein had forseen a brilliant and diabolical idea…
WHITE TO PLAY AND WIN!

Wolf Heinrich
gm Bogoljubov,E
Pistyan 1922 Position after 27 moves of play. White has an obvious advantage but Black seems to have everything under control. All Black needs is one move (Ne5)…however, Bogoljubov is in top form on this day and does not let Black get any play…
WHITE TO PLAY AND WIN!
