In a complicated battle Fedoseev played very enterprising chess, sacrificing a piece for the attack, but a mistake at a crucial moment cost him his advantage and left him a bit worse, after which Fridman never gave him a chance to come back.} 1. e4 e5 2. Bc4 Nf6 3. d3 c6 4. Nf3 d5 5. Bb3 Bd6 {This line is not as fashionable as it used to be. I wonder what Fedoseev had prepared against the typical Italian set-up.} 6. Nc3 dxe4 7. Nxe4 (7. Ng5 O-O 8.

Nxe4 8. dxe4 h6 {A rare choice but I am sure Fridman would know this move as his wife IM and four times US-champion Anna Zatonskih employed it against Vallejo in 2010! Nevertheless, I am a bit skeptical about this move in general. Black gives up a valuable tempo which could give White a very dangerous initiative in return.} 9. O-O (9.
