Two Puzzles from the Russian Junior Championships
Perusing the games of the recent Russian Junior Championships (congratulations to Ivan Bukavshin and Alina Bivol!), I came across the following two examples of interesting tactics. Can you solve both puzzles?
The first is perhaps more difficult to see. It comes from a game in round four between the eventual tournament winner GM Ivan Bukavshin and GM Urii Eliseev. Bukavshin played a double-fianchetto Reti with a slight twist on move twelve which allowed a speculative skirmish on the kingside that gained white some space, at the cost of weakening his own king position. As his moves kept coming quickly, it became clear that Bukavshin had worked out an interesting way to develop a strong attacking initiative. See if you can find the combination that lay behind his play (note that it does not necessarily win material in the short-term, but leads to a powerful positional advantage and attacking initiative):
