Strings

[h7dra]

Hello

Suppose I have the string s="1. e4 {0s} e5 {Biblio. 0s} 2. d3 {1s (Cf3)} Nc6 {Biblio.
0s} 3. g3 {4s} Nf6 {+0.27/7 2s} *" and the number i=3 and then I want to get the 2 strings "g3" and "Nf6" (they appear after 3. and before * in the string s) . How can i do this please?

Thanks in advance
