Whilst it’s fresh on my mind, here’s another trap featuring …Qa5+ which I once managed to land on someone myself in a Bolton Rapidplay tournament. White’s 3.e3 error has been made by quite a few strong players, probably because they identify the position as being strategically similar to the one that arises after 2…d5 and then play their ‘repertoire’ move.
This makes 2…c6 into quite a tricky move, and it’s also one of Black’s best scoring options. One further thought is that after 3.Bxf6 gxf6! 4.Nf3, there’s an echo theme with 4…e5!? (apparently a theoretical novelty) and now 5.dxe5 dxe5 6.Nxe5 Qa5+ will win the knight!
