  al wazir: 38. Kd1. Now what?
Jun-26-21  Walter Glattke: 29.-Rxa4 30.bxa4 Ka8 31.c4 Nxc4 32.Bxc4 Bxe4+ 33.Bd3 Rb8+ 34.Kc2 Qb2# 31.Qc1 Qxa4 32.Qb2 Rb8 33.Kc1 f5 34.h4 fxe4 35.Be2 e3 36.h5 d5 37.Rd4 +- / 36.-Bc6 37.Rd4 Rxb2 38.Rxa4 Rxc2+ 39.Kxc2 Bxa4+ 40.Kd3 Ka7 h-pawn wins
Jun-26-21  mel gibson: This is a nothing puzzle.
According to Stockfish 13 it agrees
with the first move but Black is only winning by 1 point.

29... Rxa4

score for Black +1.05 depth 42.

Also - when White resigns Stockfish
is calling it a draw!
Why did White resign?

  drollere: for better or worse, i went this way: 29. .. Bxe4 30. Bxe4 Nc4, 31. bxc4 Rxa4, 32. c3 Qa1+, 33. Kc2 Qa2+, 34. Kc1 Qa3+, 35. Kb1 Kc7
Jun-26-21  Brenin: Did White lose on time? <al wazir>'s suggested 38 Kd1 unpins one R, protects the other, prevents Nc4, and threatens Bxa6, so what does Black play? Wherever he moves the Q, his compensation for the exchange is looking thin. And that h-pawn could eventually be useful.

  halito27: 38. Kd1 gets into trouble after the clever 38...Qc3! The queen's immune and black picks up a nice initiative.
Premium Chessgames Member
  drollere: <38. Kd1 gets into trouble after the clever 38...Qc3!>

what's immune about 39. Qxc3? now white is up a piece, a R and a Q.

Premium Chessgames Member
  halito27: <drollere> 39. Qxc3 Rb1 mate.
Premium Chessgames Member
  drollere: <39. Qxc3 Rb1 mate.>

something must be amiss with the board animation or the rendered position. i play 40. Kxb1 and can't see any reason why not.

Jun-26-21  Walter Glattke: White could have lost by time - 40 moves in 2h

  agb2002: Black is one pawn down.

White threatens Qxa5, the queen x-rays d6 and if all the pieces disappeared then h4 would win the pawn ending.

Black can resume the attack against the white castle with 29... Rxa4 30.bxa4 Ka8. For example, 31.Qc1 Qxa4 (31... Qc5 looks interesting) 32.Qb2 Rb8 33.Kc1 Qa5 with the threat Bc6-Rb4-Ra4.

  pittpanther: I too am puzzled by today?s puzzle!

Hope chessgames can get their issues sorted through.

Jun-26-21  George4790: The threat is Pc4. With all kinds of terminating moves coming from it. There seems not much that white can do to ease this.

Jun-26-21  George4790: White cannot chase the queen away, not defend the castle at d2, e2 is pinned as is d2, so what is left? The White queen has no field to help defend d2. So totally Lost!

  halito27: <drollere> We're talking about the position after 38. Kd1. Read back: I said IF 38. Kd1, then Qc3 is the retort. At that point, after 39. Qxc3, the white king is no longer in position to capture the rook on b1.
Premium Chessgames Member
  halito27: Once again, <chrisowen> seems to have gotten it right. "lecture vindicate dazzle i vast japs maps jams buzzy waggy firk" is especially astute.
Jun-26-21  njchess: The rook sac is pretty obvious. 30. ... ♔a8 less so, but a necessary move for the attack. The ending is a bit strange. White is up material but will struggle to get any attack going. Black has lots of options but White can defend with accurate play. I'm thinking it was a time control issue for White as has been suggested.

  chrisowen: No treats a kinder a4 no?
Jun-26-21  Petrossian: <halito27> can you please decipher what <chrisowen> said?
Jun-26-21  StevieB: I've noticed the engine isn't working for a few days now. Anyone know why?
Jun-26-21  dhotts: The final position is positive for White 39. Rf1....Strange calling the position a puzzle, as Black merely stays even at best...White must have lost on time...Forcing White to find the Best Defense takes more time than attacking...So maybe from a psychological/time perspective, putting pressure on the Black king is a winning strategy!
Jun-26-21  Ivan Karamazov: <Petrossian: <halito27> can you please decipher what <chrisowen> said?>

He really doesn't have to. It really just speaks for itself.
