Oct-30-10		LivBlockade: After 9. d5!, Black's position is already difficult.

Dec-07-22		jrredfield: I went with the text move 24 Rxe7 right away but it took a bit longer to see the combination to pin the Black Q with the corner R. It's a close call between a number of good moves for White. This seems to be the theme this week: multiple solutions to POTDs. Here's the four best moves for White per Stockfish 15.1 (depth 30): +6.76 24.♖ad1 ♕c6 25.♖c1 ♕f6 26.♕xd7 a5 27.♖c3 g4 28.♖ce3 a4 29.♗c4 b5 +6.67 24.♖xe7 ♔xe7 25.♗d5 ♕b8 26.♕d4 ♕f8 27.♗xa8 ♔d8 28.♗f3 ♖e7 29.♕d5 ♖e6 +6.64 24.♖e5 ♕c6 25.♖ae1 d5 26.♖xd5 ♘xd5 27.♗xd5 ♕f6 28.♗xa8 ♖f7 29.♕a3+ ♔g7 +6.42 24.♖ac1 d5 25.♕f3+ ♖f7 26.♕h5 ♖g7 27.♕h8+ ♘g8 28.♖e5 ♖c8 29.♖ce1 ♖d8

Dec-07-22		Steve Holloway: I only saw 24.Rxe7 Rxe7 25.Qd4 winning, and 24.Rxe7 Kxe7 25.Bd5 winning

Dec-07-22		Brenin: The exchange sac 24 Rxe7 looks promising, with 25 Bd5 as a follow up regaining material and continuing the attack, or with 25 Re1+ first if 24 ... Kxe7.

Dec-07-22		Lambda: I had 25.Re1+ Kd8 26.Qf5 with a slightly odd position in which black has no way to save the rook on g7. click for larger view

Dec-07-22		mel gibson: I agreed with the text move: 24. Rxe7. Stockfish 15 chose a different move: 24. Re5 (24.

Dec-07-22		ajk68: After looking at Rxe7, I settled on Qh3 - which is still winning. 1) +16.57 (40 ply) 24.Rxe7 Kxe7 25.Re1+ Kd8 26.Bd5 Qc7 27.Qe2 Qc5 28.Qe8+ Kc7 29.Qxa8 Re7 30.Qxa7+ Kd6 31.Rd1 Qxd5 32.Qxb6+ Ke5 33.Rxd5+ Kxd5 34.Qb5+ Kd6 35.Qb4+ Ke6 36.Qc5 g4 37.Qc4+ Kf6 38.Qf4+ Ke6 39.Qxg4+ Kd6 40.Qb4+ Ke6 41.g3 d5 42.Qb6+ Kd7 43.Qc5 Re5 44.Kg2 Rf5 45.Qb5+ Ke7 46.Qc6 Rg5 47.Qc7+ Ke6 48.Qc8+ Ke7 49.Qc6 Rf5 50.Qc7+ Ke6 51.Qc8+ Kf6 52.Qd7 Rg5 53.Qd6+ Kf7 54.h4 2) +16.1 (40 ply) 24.Rad1 Qc6 25.Qh3 Rd8 26.Qh8+ Ng8 27.Bxg8 Rxg8 28.Qe5 Rg7 29.Rd6 Qxd6 30.Qxd6+ Kg8 31.Re7 Rxe7 32.Qxe7 Rc8 33.g3 Rc5 34.Qd8+ Kf7 35.Qxd7+ Kf6 36.Qxa7 Rc6 37.Qd7 Re6 38.Kg2 Ke5 39.Qb5+ Kf6 40.Qd5 Re5 41.Qd6+ Re6 42.Qd8+ Kf5 43.Qd5+ Re5 44.g4+ Kf6 45.Qd7 Re6 46.Qc7 Kg6 47.Qd8 Kf7 48.Qxg5 Rd6 49.h4 Ke6 50.h5 Kd7 51.h6 Kc6 52.h7 3) +11.68 (39 ply) 24.Qh3 d5 25.Qh8+ Ng8 26.Re5 Qf7 27.Bxd5 Qf6 28.Re6 Qf5 29.Re7 Qg6 30.Rxg7 Qxg7 31.Qxg7+ Kxg7 32.Bxa8 Nf6 33.Rc1 Ne8 34.Rc8 Kf7 35.Bc6 Nd6 36.Rc7+ Ke6 37.Rxa7 Nc4 38.b3 Ne5 39.Be4 Kd6 40.Rg7 g4 41.Bf5 g3 42.hxg3 Kc5 43.Be4 Kd6 44.Ra7 Kc5 45.Rb7 b5 46.Bf3 b4 47.Rb8 Nd7 48.Rc8+ Kd6

Dec-07-22		Brenin: Yet another POTD in which almost any sensible move seems to win, e.g. 24 Rad1 Rd8 25 Rxe7, and if 25 ... Kxe7 then 26 Qd6+ with mate in a few moves, while 25 ... Rxe7 is answered with 26 Qf5+, again leading to mate.

Dec-07-22		King.Arthur.Brazil: One line is 24. ♖xe7 ♖xe7 25. ♗d5 ♕c8 26. ♕f5+ ♔g7 27. ♕xg5+ ♔f8 28. ♕h6+ ♖g7 29. ♕h8+ ♔e7 30. ♕xg7+ ♔d6 31. ♖d1 (If 27... ♔f8 28. ♕h6+ ♔e8 29. ♕h8#). Or 29... ♔g7 30. ♕g5+ ♔h8 31. ♕e5+ ♕g7 32. ♕xg7+ ♔xg7 33. ♗xa8 with easy win. Another line is 24. ♖xe7 ♔xe7 25. ♖e1+ ♔d8 26. ♗d5 ♕c8 27. ♕e4 ♖b8 28. ♕e8+ ♔c7 29. ♖c1+ ♔d6 30. ♖xc8 ♖e7 31. ♕g6+ ♔xd5 32. ♕xg5+ ♔d6 33. ♕xe7+ ♔xe7 34. ♖xb8. Maybe, there must be a more quickly sequence. The King is not so brain tonight. Sorry.

Dec-07-22		agb2002: White has a bishop and a pawn for a knight. The knight controls d5. This suggests 24.Rxe7: A) 24... Rxe7 25.Bd5 Qb(c)8 26.Qf3+ and 27.Bxa8 wins a piece. B) 24... Kxe7 25.Bd5 Qb(c)8 26.Qe4+ as above.

Dec-07-22		saturn2: I went with 24.Rxe7 followed by Qf5

Dec-07-22		Chessius the Messius: Missed it with Qh3, while I could have known it's another battery puzzle. Such a dummy

Dec-07-22		sfm: <LivBlockade: After 9. d5!, Black's position is already difficult.> Here, 12 years after your posting, a MrEngine claims that actually Black is OK after 9.-,0-0 But the played 9.-,exd5? 10.cxd,Nxd5? is downhill, and 11.Nxd5,Bxd4 12.Nf4,Bb7? is over. Nice demonstration by White

Dec-07-22		chrisowen: I chucker fave its mad baroque its Rxe7 abridge its lag cha ignoble its cad cinch its Rxe7 eithad;

Dec-07-22		Cellist: I saw the first move, but expected Black to take not with the King but the Rook. After Kxe7, I wanted to play Re1+ first, before Bd5, and that works very well, too. Black's position is weak, with the K fairly exposed. Many possibilities exist to take advantage of this.

Dec-07-22		Fusilli: I was quite lazy here. I barely calculated, because white's superiority is so overwhelming and the themes so many that there is no way the sac doesn't win. On a different note, black is pretty much lost after the ridiculously insane 10...Nxd5. Wasn't this the top Bulgarian GM of his time? Hard to believe he would be so reckless. (Unless it was an arranged game.) Nunn says in one of his books that the masters of the early 20th century would be low-level players at best now (I am paraphrasing poorly, but you get the idea.) We learn from the classics because defense is so weak that those old games have pedagogical value in helping us learn basic principles. (See why development is important? See what happens when you let your pawn structure go to hell?) Now I am increasingly wondering whether that is true even for mid- and late-20th century GMs.

Dec-07-22		TheaN: <24.Rxe7 with 25.Bd5 +-> is just not hard to spot, and even though Black can prevent material loss on the short term, the position's in shambles. Okay Wednesday, but on the easy side.

Dec-07-22		Cheapo by the Dozen: It's easy to see the combination of saccing the exchanging, winning the exchange back, and thus simplifying. It seemed promising to pin the surviving black rook and simplify further. But before I completely worked that out, I saw the idea of indeed winning a piece. :)

Dec-08-22		saturn2: <TheaN: 24.Rxe7 with 25.Bd5 +- is just not hard to spot, and even though Black can prevent material loss on the short term> <agb2002> has shown material loss comes after two moves.

Mar-12-24		N.O.F. NAJDORF: 12...Be6 13. Nxe6 dxe6 14. Qf3 Nd7 15. Bb5 Rc8 16. Rd1 Rc7 17. Bf4 12...Be6 13. Nxe6 fxe6 14. Qh5+ g6 (Kf8 15. Qf3+) 15. Bxg6+

Mar-12-24		N.O.F. NAJDORF: <Steve Holloway: I only saw 24.Rxe7 Rxe7 25.Qd4 winning, and 24.Rxe7 Kxe7 25.Bd5 winning> That is a very interesting idea! 24. Rxe7 Rxe7 25. Qd4 Rf7 26. Re1

Mar-12-24		N.O.F. NAJDORF: <TheaN: <24.Rxe7 with 25.Bd5 +-> is just not hard to spot, and even though Black can prevent material loss on the short term, the position's in shambles. Okay Wednesday, but on the easy side.> In his column in the Daily Telegraph, B.H. Wood pointed out that white had to play 23. Qd3 before 24. Rxe7.
