My Favourite line
Well no particular reason:
1. e4 e5 2. Nf3 Nf6 3. Nxe5 d6 4. Nf3 Nxe4 5. d4 d5 6. Bd3 Bd6 7. O-O O-O 8. c4 c6 9. Re1 Bf5 10. Qb3
Classical Attack, Marshall Variation That was also the first main line I learnt back then:
1. e4 e5 2. Nf3 Nf6 3. Nxe5 d6 4. Nf3 Nxe4 5. d4 d5 6. Bd3 Bd6 7. O-O O-O
The next moves are usually 8.c4 c6 9.c6… However, please also note the Marshall Trap:
8.c4 Bg4 9.cxd5 f5 10.Re1? Bxh2+!
Note: With correct play this position can be drawn! The computer evaluates (-0.5) so the advantage is very minimal!
Obviously 11.Nxh2?? loses the Queen and we don’t do this.
If you are greedy and play 11.Kxh2, black can strike back with 11…Nxf2! , forking the Queen and the Bishop at the same time.
After a number of exchanges, e.g.12. Qe2 Nxd3 13. Qxd3 Bxf3, you cannot take back the bishop or else you will be met by 14.Qh4!! and your rook is lost!
