1. d4 Nf6 2. c4 c5 3. d5 Ne4 4. Nd2 Qa5 5. Ngf3 g6 6. b4 1-0

It's been played before, but not everyone has spotted 6. b4 . It's possible to play on for a bit

eg 1. d4 Nf6 2. c4 c5 3. d5 Ne4 4. Nd2 Qa5 5. Ngf3 g6 6. b4 Qxb4 7. Rb1 Nc3 8. Rxb4 Nxd1 9. Rb3 Nxf2 10. Kxf2 Bg7

leading to

rnb1k2r/pp1pppbp/6p1/2pP4/2P5/1R3N2/P2NPKPP/2B2B1R w kq - 1 11

which might be playable if Black out-rated his opponent by a reasonable margin.

Two pawns for a piece is usually worth playing out IMO (unless the position is obviously lost for other reasons, of course)

There is even a game in the databases - between rated players - where Black managed to lose after 1d4 Nf6 2Bg5 c6 3e3??? Qa5+
