Often while playing I'm forced to make certain moves in an opening in order to defend against certain obvious attacks. I would like to ask a question to identify an opening that either my opponent is playing, or I'm defending/attacking against. Sometimes plugging the moves into google yields the results, sometimes it doesn't. For example:
Can anyone tell me the name of the opening white used in this game?
[fen ""] 1.e4 c5 2.Nf3 Nc6 3.d4 b6 4.Nc3 Bb7 5.d5 Nd4 6.Nxd4 cxd4 7.Qxd4 f6 8.Be2 e5 9.dxe6 dxe6 10.Qxd8+ Rxd8 11.O-O Bd6 12.Be3
Would a question of this type be on topic? It has a definitive answer, even if that answer is 'White started with [chess opening], but transposed into something else' or something similar.
