    Modern Defense: Masur Gambit is a chess opening that arises after 1.e4 g6 2.d4 Nh6 3.Nc3 f5 4.Bxh6 Bxh6 5.exf5 O-O. It is classified B06 in the ECO system, and the position after these moves has white to move. The Modern Defense fianchettoes immediately, delaying the knight development that would define it as a Pirc. This maximum flexibility lets Black choose the structure after seeing what White commits to.

    Strategic character

    Extremely flexible and transpositional — the Modern can turn into a Pirc, a King's Indian, or something entirely its own. That flexibility is also its cost, since Black concedes the centre early and must handle a wide range of White setups.
