I think black should play 25...Ra6, because in this position white cannot fork, as white then loses the d pawn.
Seed of Destruction
Sort:
25... Rxa5?? is not black's best move, but I think it would be difficult to resist a hanging knight.
25... Ra6 is better but still not black's best and white wins a Rook for 2 pawns and White is winning.
See what I mean...tactically complicated position...
Nicely spotted, 'Weak Back Rank', another one of DHs 'SoTDs'. The more seeds the more chance of finding a winning tactic.
This is a position I reached in a 45/45 game yesterday. I played 25 Nc6 which was a blunder. However, I am not going to chastise myself too much as this was quite a complicated tactical position. Anyway, the Seed of Tactical Destruction in Black's camp was the discovered attack on the Rook.
