C54/c50,c53 Italian [giuoco piano] Discovery 1

Discoveries (theoretical novelties) in C54 Italian Game (Giuoco Piano) /c50 Giuoco Pianissimo, c53 Birdís Attack/, changing appraisal of its very important systems, are present in this investigation.

Summary of analysis (author's novelties are marked by symbol "AN")

C54 Part 1: 1. e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.c3 Nf6 5.d3 (5.b4)

Paragraph 1: 5.d3 a6 6.0-0!

I. 6...d6

[6...b5?!AN(White stands better.); 6...0-0?AN 7. d4! Bb6 (The move 7...Ba7 does not change matter.)-6...Bb6; 7...ed? 8. cd Bb6(or 8...Ba7) 9.d5! (White stands better.); 7...Be7 8.de(White stands better.)] 7.d4!AN Bb6 (or 7...Ba7; 7...ed 8.cd(White stands better.)) 8. de! (White stands slightly better.)

II. 6...Bb6AN 7.d4! ed

[7...d6- 6...d6; 7...Qe7(White stands slightly better.); 7...0-0 8. Ne5! Ne4 9. Nf7! Rf7 10. Bf7 Kf7 11.Qh5 Kf8 12. Qh7! Nf6 (12...d5 13.Nd2! Nd2! 14. Bd2 (White stands better and has the attack.)) 13. Qh4! (White stands better and has the attack.) ;8...Ne5 9. de Ne4 10. Bd5!?(with the idea Bf4) (White stands slightly better.) ; 7...Ne4 8.de!? (White stands slightly better.)] 8. cd !? (White stands better.). The moves 8...d5 and 8...Ne4, that open the line "e", lead to very vulnerable position of black king. That is why we shall not consider such interest moves, as 8. e5, 8. Bg5, 8. Re1, 8. Nd4.

III. 6...Ba7 7.d4!AN

(6...Qe7AN 7.d4!-6...Bb6, 6...Ba7). This position is analogous to one, that arises after 6...Bb6 7.d4!

IV. 6...Be7!AN 7. d4! d6

(7...ed? 8.e5 (White stands better.);
7...0-0 8.de (White stands slightly better.);
7...Ne4 8.de (White stands slightly better.);
7...Na5 8.Bf7!? Kf7 9.de (White stands better.))

A) 8. de Ne5! 9. Ne5 de. White stands a very small chance to advantage after 10.Qc2! (or 10. Qe2!) with the idea 11.Rd1, 12.Nd2.

B) 8. d5 Nb8 9. Bd3 h6!? (With unclear position.)

C) 8. Qc2! (White stands slightly better.)

It should be noted, that a good move 5...Be7!?AN is possible, but we shall omit its consideration. We are going to consider the strongest black's answer to 5.d3.

Paragraph 2: 5. d3 0-0!

{The idea d7-d5 was realized after 5. d3 0-0 only once (Gelfand -Shirov, 1993) and didn't get further development. White could play stronger in this game after 6. b4 Bb6: 7.Bg5!AN(with unclear position) [7.0-0?! d5!? (7...d6!=) 8. ed Nd5 9.b5!?AN (with the idea Ne5)]. After that the move d7-d5 (or d6-d5) would be impossible.}
