Here black attacks both the Bc4 and the pawn e4. White has a couple of moves: 5. exd5 5. bxc5 5. Bxd5 5. c3!? 5. Bb3!? 5.exd5 removes the attacker of the c4 bishop, and counterattacks the knight. Black has two pieces hanging in the middle of the board - however, black can escape with 5...Nxb4, saving the knight and remove the attacker of the C5 bishop. 5. bxc5 opts for a bishop trade, but after the trade, the c4 and C5 pawns are both double and weak, and can be attacked easily. 5. Bxd5 captures a pawn - however black can also capture a pawn like with 5...Bxb4 and material is even. 5. c3!? is a dubious choice against the Hein Countergambit as it doesn't deal with most threats, however it defends the pawn B4 that could have been captured by the Bc5. 5. Bb3!? is another dubious choice against the Hein Countergambit that retreats the bishop to a safe square but it leaves a pawn hanging, but material is eventually equal (5...Bxb4 6. exd5 (6...Qxd5?? is not possible due to 7. Bxd5) or 5...dxe4 6. bxc5 exf3 7. Qxf3). 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.b4 d5
