 | | Ron: Came across this fine game by Jacques Mieses from the Random Game feature.
Instead of 34. b3, Mieses has a forced mate, at most, in seven moves, with 34. Re7. Here is a computer checked line: 34. Re7 Qd1+ 35. Kh2 Qg4 36. Rf7+ Ke8 37. Qe5+ Qe6 38. Qxe6+ Kd8 39. Qe7+ Kc8 40. Qxc7 mate |

| May-18-05 | | JohnBoy: After 34.b3 Qxa2, doesn't 35.Re8+ Kxe8 36.Qc8+ Ke7 37.Qe6+ do pretty much the same thing? |

Stockfish 17 chooses a different ply:
30. c5
(30. c5 (1.c5 bxc5 2.Rxe5 dxe5 3.Rxe5 Rf8 4.Nxc5+ Kd8 5.Nxd7 Nxd7 6.Qg5+ Rhf6 7.Re1 Nb6 8.d6 cxd6
9.h4 R8f7 10.Kh1 Nc8 11.a4 Rc7 12.Bh3 Re7 13.Rc1 Nb6 14.Qa5 Ke8 ) +7.87/45 249) score for White +7.87 depth 45.
if I force SF to play the game ply it's slightly better: 30. Rxe5 dxe5
(30. .. dxe5 (1. ... dxe5 2.Rxe5 Rf8 3.Nc5+ Kd8 4.Nxd7 Nxd7 5.Qg5+ Rhf6 6.Re6 R8f7 7.Kh2 Rf8
8.d6 cxd6 9.Rxd6 Ke7 10.Rd1 Nc5 11.Qxg7+ R8f7 12.Qg5 Ne6 13.Re1 Kf8 14.Qxh5
a5 ) -8.18/44 276)
score for Black -8.18 depth 44. |

But c4-c5 shows the hand of the artist. :-) Also, if you asked me to guess who was playing Black, I wouldn't have come up with Tarrasch very quickly. Also, 34.Re7 is a pretty crazy mating move. |

| Sep-11-24 | | Mayankk: 30 Rxe5 dxe5 31 Rxe5 Kf7 (to protect his majesty from discovered checks) 32 Ng5+ Kf8 33 Re6 is all very obvious. But then I got stuck. I didn't realise how helpless Black was against the threat of 34 Rxf6+ gxf6 35 Qxd7 and if Black Queen moves then 34 Re8+ Kxe8 35 Qe6+ Kd8 36 Nf7# or 34 Re7 Kxe7 35 Qe6+ with the same result. Tough one. |

| Sep-11-24 | | saturn2: After 31.Rxe5 dxe5 I took 42.Rxe6. Now the thrwat is Nc5. thetefore 42...Kf7 and now what? Probably 43.Ng5 followed by Re6. White is an exchange
down and has still some grinding work to do. |

| Sep-11-24 | | TheaN: Wasn't entirely sure about this one but I think I did find a different idea that works pretty well too: <30.Rxe5 dxe5> alternatives just allow White to retreat a piece up <31.Rxe5 Kf7> also here, alternatives are not to be considered as Black will lose the queen... or king after 31....Qc8? 32.Ng5+ Kd8 33.Nf7#:

The exchange sac does make perfect sense even positionally. Black's rooks are useless, and we have a rather quick way to activate the one piece of White that's idle. That's what I chose actually: <32.d6!?>. Eventually White will want to play this anyway to allow the threats of Bd5 and Bc6 to come into play as well. However, after <32....cxd6> I initially wanted to play 33.Bc6?, but that doesn't work after 33....Qxc6 as White invested too many pieces and perpetual is left with 34.Ng5+ Kf8 35.Ne6+ =. Instead, White can just play the text moves 33.Ng5+ Kf8 34.Re6 +- and we're essentially back in the game's territory. I chose the slightly lamer but also winning rook retreat <33.Re1> (Re2 or Re3 are actually better as Rxe1 doesn't come with a check later), considering White will play Bd5 next and Black's as good as paralyzed: <33....Re8 34.Bd5 +->. SF here gives 34....Re7 but then simply 35.Nc5+ Ke8 36.Nxd7 Rxe1+ 37.Kf2 +- wins. |

| | keypusher: <scormus: Aaaah! Got every move except the last, 34 b3! The quiet assassin. Cool Hand Luke.> 34.Re7 forces mate, so I don't think you lose points for 34.b3, depending on what else you came up with. |

| | scormus: <keypusher: 34 Re7> Thanks, I'll take that! It's what I had in mind but it looked rather messy and I didn't pursue it all the way to #. By contrast b3 is neat and elegant |
