Robert Ris: "I have a look at the game Dubov-Isanzhulov from the FIDE World Blitz team championships in Kazakhstan. In a King's Indian (1.d4 Nf6 2.Nf3 d6 3.c4 g6 4.Nc3) with 4...Bf5 White played the principled 5.Qb3 and after 5...b6 opted for the almost unknown 6.e4!?, which is a spectacular pawn sacrifice that gave White great chances to develop the initiative. Soon, Dubov also launched his g- and h-pawn.
The ensuing positions are fascinating to analyse, but unfortunately on move 24 Black lost on time."
Question: How would you continue here with White?
