The Closed, Spassky Gambit is a variation of the Catalan Opening, catalogued as ECO E08. The line runs 1. d4 Nf6 2. c4 e6 3. g3 Be7 4. Bg2 d5 5. Nf3 O-O 6. O-O Nbd7 7. Qc2 c6 8. b3 b6 9. Rd1 Bb7 10. Nc3 b5, reaching the position shown below after 20 half-moves.
Both sides have pawns in the centre (White on d4, Black on d5), and two pawn captures are available, so the structure is still fluid. Development is level at three minor pieces each. It is White to move after ten moves. Both kings have castled kingside, so play tends to shift to the centre and the opposite flank.
On the Catalan Opening generally: A sophisticated system combining Queen's Gambit ideas with a fianchettoed king's bishop.
