The game Moiseenko-Onyshchuk from the Ukrainian Championships features a fascinating attacking idea in the Austrian Attack of the Pirc (4.f4).
In these lines Black likes to exchange his light-squared against White's knight on f3, and usually White recaptures on f3 with queen or rook. But in his game against Onyshchuk, Moiseenko decided to recapture with his g-pawn, which enabled him to develop an attack on the g-file.
Exercise: Would you exchange rooks on a8 or keep them on the board?
