However, 3.Nf3 is often played instead as a way of avoiding the <a href="/wiki/Nimzo-Indian_Defence" title="Nimzo-Indian Defence">Nimzo-Indian Defence</a> (which would follow after 3.Nc3 Bb4). After 3.Nf3, Black usually plays 3...b6 (the <a href="/wiki/Queen%27s_Indian_Defence" class="mw-redirect" title="Queen's Indian Defence">Queen's Indian Defence</a>) or 3...d5 (transposing to the <a href="/wiki/Queen%27s_Gambit_Declined" title="Queen's Gambit Declined">Queen's Gambit Declined</a>), but can instead play 3...Bb4+, the Bogo-Indian Defence.
