Can anyone tell me what happened here ? What is this opening ?
r3k2r/p2RQ3/q3b2p/2p2p2/4N3/8/1PP3PP/6K1 b - - 11 27
Why are 9...Nd7 and 10...Nf6 blunders ?
10...Nf6 is a blunder because if 11. Bf7+ , King has to move letting Queen unprotected, if 11...Kxf7 12.Qxd8, otherwise, if 11...Ke7 12. Re1...
@Chessminator172 to deal with this opening play 1.d4 Nf6 2.Nc3 d5 3.e4 Nxe4 5.Nxe4 dxe4 6.f3 e5!
