Kibitzer's Corner
Apr-18-16  sreeskamp: In the database of CG.com scores b3 very badly for black. Even Simon Williams can not make chocolate out of it (Dutch saying).
Sep-30-23  Brenin: My idea was 25 Rxf5 Qxf5 followed by an immediate 26 d6, or possibly Rf1 first, to get those pawns rolling forward. Taking Black's h-pawn seems a needless distraction from the main theme of the combination.
Sep-30-23  raymondhow: I chose the first three moves, then wanted to play 28.d6 which the engine prefers to the game move. Have to call that a solve, but it's not really a great puzzle because the initial positional sacrifice is rather obvious.
Sep-30-23  mel gibson: I chose 25. c5 to use the power of 2 connected passed pawns.

Stockfish 16 follows the game line saying:

25. Rxf5

(25. Rxf5 (Rf1xf5 Qg6xf5 Qe2xh5 Qf5-h7 Qh5xh7+ Kg8xh7 c4-c5 Ra8-h8 d5-d6 Re7-e8 b3-b4 g5-g4 Ra1-g1 Re8-e6 Rg1-f1 Kh7-g8 Ne4-g3 e5-e4 Bg2xe4 Re6-h6 Rf1-f2 Nf7xd6 Be4-d5+ Kg8-h7 c5xd6 Rh6xd6 Bd5-e4+ Kh7-g8 Ng3-f5 Rd6-d7 Kh1-g2 Bg7-f6 Rf2-f4 Bf6-c3 Rf4xg4+ Kg8-f8 h2-h4 Rh8-g8 Rg4xg8+ Kf8xg8 Kg2-f3 Bc3-f6 b4-b5 Bf6-d8 a2-a4 Rd7-c7 Be4-d5+ Kg8-h7 Kf3-e4) +3.35/43 423)

score for White +3.35 depth 43.

if I force SF to follow my idea it's slightly better:

25. c5

(25. c5 Nh6 (Nf7-h6 d5-d6 Re7-f7 Nd3-b4 Kg8-h8 Nb4-d5 Bg7-f8 b3-b4 g5-g4 Ra1-e1 h5-h4 h2-h3 g4xh3 Bg2-f3 h3-h2 Rf1-f2 Bf5xe4 Bf3xe4 Rf7xf2 Qe2xf2 Qg6-g3 Re1-f1 Qg3xf2 Rf1xf2 Bf8xd6 c5xd6 Ra8-d8 Rf2xh2 Rd8xd6 Rh2xh4 Kh8-g7 Kh1-g2 Rd6-a6 Nd5-c3 Ra6-f6 Be4xb7 Rf6-b6 Bb7-d5 Nh6-f5 Rh4-g4+ Kg7-f6 Kg2-f2 Nf5-d4 Bd5-e4 Kf6-f7 Kf2-e3 Rb6xb4 Ke3-d3 Rb4-b2 Rg4-g5 Kf7-f6 Rg5-g6+ Kf6-e7 Rg6-a6 Ke7-d8 Ra6-a5 a7-a6 Nc3-d1 Rb2-h2 Nd1-e3 Kd8-c7 Ra5xa6) -3.84/44 911)

score for Black -3.84 depth 44.

Sep-30-23  Mayankk: The positional exchange sacrifice is easy to spot since Black light-squared Bishop is a key defender and White will dominate the light squares after it.

But after 25 Rxf5 Qxf5, White has many paths to choose from. My initial thought was to anchor one Knight at e6, Bishop at e4. Rook on the open f file while attack with the other Knight and Queen. I wasn't sure if an immediate pawn push will weaken the nice pawn structure White has and maybe a better idea was to improve the positioning of White pieces and wait for the right time to push them forward.

  scormus: A very positional sequence with decisions to be made at almost every move. As it was a puzzle, I opted for 25 Rxf5, intending the continuation ... Qxf5 26 Rf1. I wasn't sure about 26 Qxh5. After ... Qh7, 27 Qxh7 seemed the logical follow up, but I didn't think it looked decisive. Wondered about retreating the WQ instead.

I see <mel SF> follows the game, so it looks like I lost the way here.

  LIFE Master AJ: To me, this is an insane puzzle. The opposite colored, R+B+P's endgame is VERY difficult ... i maybe thought for over half and hour to try and solve this puzzle.

I found the key move, RxB/f5, but it was so hard, i did not get all the moves of the combination.
