whats your nezt move?!!!

The usual move is 2.exd5
Then B can choose between 2 options:
-2...Qxd5 3.Nc3 Qa5(Qd8 and Qd6 also possible but this is the mainline) 4.d4 Nf6 5.Nf3 c6 6.Bd2 Bf5 7.Bc4(7.Ne4!?) e6 8.Nd5 Qd8 9.Nxf6 and now either 9...gxf6 or 9...Qxf6. This is the absolute mainline. Other interesting setups are avaiable for W of course.
-2...Nf6 3.Bb5+(this is recommended in some repertoire book. By forcing Bd7 W avoid some dangerous gambits) Bd7 4.Be2 Nxd5 5.d4 Bf5 followed by natural development with 0-0.c4,Nc3,Be3.
And also if you can please say me 3 or more moves after your move at the first . Thanks
