| Nov-21-23 | | Brenin: White wins a P, and hence the endgame. with 20 Rxd6+, e.g. 20 ... Rxd6 21 Nxb7 Rd7 22 Nc5+, regaining the exchange, or 20 ... Kxd6 21 Nxb7+ and 22 Nxd8. |

the advantage is small.

| Nov-21-23 | | Mayankk: After 20 Rxd6+ Rxd6 ( 20... Kxd6 results in an immediate 21 Nxb7+ fork) 21 Nxb7, White's d6 Rook has nowhere safe to go. After 21 ... Rd7 22 Nc5+ Ke7 23 Nxd7 Kxd7 e.g. White is a pawn up. Now is a pawn advantage good enough in a Rook endgame with 6P vs 7P? I don't know tbh, given how tricky Rook manoeuvres can be and how difficult it is to preserve a pawn advantage in such cases. |

 | | OhioChessFan: 20...Rxd6 seemed right to me. |
|
| Nov-21-23 | | saturn2: White gets a pawn. Aftet Nxb7. the Rd6 can only walk into a fork or be captured. |
|
| Nov-21-23 | | TheaN: As mentioned the puzzle today is the best move but not a clear cut win <20.Rxd6 Rxd6 21.Nxb7> and the rook is trapped, Black gets some compensation but not enough. |
|
| Nov-21-23 | | patz8491: If 20...Rxd6 21.Nxb7, the rook has nowhere to go. If Re7, Nc5 forks the K and N. |

| Nov-21-23 | | gofer: <cocker>: <<"A very premature resignation by my standards.">> Yes - a lack of fighting spirit never got anyone very far... << "What's the plan?">> If the black rook moves anywhere else on the g file, then white is 2 pawns up.
If the black rook stays on g5, then white plays Rg3 trading rooks. A couple of moves later we might get to...
click for larger viewOnce the rooks are off the board, things are simpler to calculate. Stockfish thinks white can simply walk his king into the black's queenside pawns faster than Black can walk his king into white's kingside pawns. Black isn't dead, but he is not looking a win any time soon. After the king walks + promotions we might get something like...

 | | gawain: That's it? I could have looked all day and still be looking. Usually "easy" wins are more conclusive than this. But this is a GM game after all. Easy for them. Meanwhile, points to me for at least seeing the forks. |
