Abstract: We give a formula for the number of plane curves of degree $d$ and genus $2$ with fixed complex structure passing through $3d\!-\!2$ points in general position. This is achieved by completing the Katz-Qin-Ruan approach. This paper’s formula agrees with the one obtained by the author in a completely different way.
