GM Jeffery Xiong

had his back to the wall and was in a must win situation facing GM Jan-Krzysztof Duda

in the FIDE World Cup. Fortunately, the American had the white pieces for the coming battle. In that situation, after the opening moves of 1 e4 e5, what would you play? Jeffery Xiong decided to play “The truth-as it was known in those far-off days.” (https://xpertchesslessons.wordpress.com/?s=the+truth+as+it+was+known+in+those+far+off+days)

(https://samshankland.com/store/)

that one should be extremely careful about moving a pawn forward because it cannot retreat. Maybe Duda should have read the book?

Yu vs Bu

1. e4 e5 2. Bc4 Nf6 3. d3 Nc6 4. Nf3 (Back in the day the only move I played was 4 Nc3. If one played the BO that was the accepted way to play. When checking the game at ChessBomb I noticed the Stockfish program showed the move 4 a4 as best. SF and Houey at the CBDB show 4 Nf3 as the best move. After 4 a4 SF at the Bomb gives this variation: (4. a4 Bc5 5. Nf3 O-O 6. O-O d5 7. exd5 Nxd5 8. Nbd2 Bb6 9. Re1 Bg4 10. a5 Bxa5 11. h3 Bh5 12. g4 Bg6 13. Nxe5 Nxe5 14. Rxe5 c6 15. Ne4).
