Puzzle #251 solution:
Rysan – Drtina, Slovakia 1993. Anya's answer:
"a) I think the opening is four knights opening
b) If white plays 10. 0-0... Then I think black will play:
10... b5 (Trapping the queen, queen has to take)
11. Qxb5 axb5 (Black wins a queen for a pawn)
c) For black to gain advantage I think he should get white's almost trapped queen or a knight. The following moves for this to happen is:
10...  Bb4 (trapping the queen and pinning  the knight)
11. 0-0 b5 12.Nxb5 13. axb5, Qxe5 (wanting to fork)
14. Bd7 (preventing fork, black wins a knight for two pawns)"
