| Dec-04-07 | | micartouse: What the heck happened in this game between the two titans? I'm curious to know when White went wrong and if he was ever better. Pillsbury tried the same QGD setup with c4-c5 and Ne5 that blew Winawer off the board in 21 moves: Pillsbury vs Winawer, 1896. It looks quite pleasant for White after 15 moves: he gets a couple knight outposts, some space, and his opponent's bishop is restricted. So White gets an outpost, then a material advantage, then an attack ... and then Black suddenly consolidates and runs a pawn up the board and wins all the while his bishop is on the back of the board. Poor Pillsbury with his orderly, inventive chess mind had to deal with chaos masters like Chigorin and Lasker who just plain won games concretely. |

| Dec-04-07 | | Calli: 29.Ra3 looks suspicious because it unguards the d pawn. 29. Qd2 looks better. Later Pillsbury should play the Q back, 40.Qh6 -Qh4-f2 and should at least draw. |
|
| Dec-05-07 | | micartouse: Thanks <Calli>. Ra3 hardly seems like an awful blunder though. It must just be a really well played game by the Russian! |

 | | Pawn and Two: <micartouse & calli> A review by Fritz indicated winning chances for White at move 29: (1.52) (21 ply) 29.Qe5 Rb7 30.Ra3 f6 31.Qxc7 Rxc7 32.Rxa5 Rxd4 33.Ra8 Kf7 34.a4. Fritz's evaluation now is: (2.17) (18 ply) 34...Rd5 35.Rc3. Additional Fritz analysis from this point indicated good winning chances for White. Fritz's 2nd choice at move 29 was: (1.50) (21 ply) 29.Rb3. Fritz's 13th choice was: (.97) (21 ply) 29.Ra3 Rxb6 30.cxb6 Qxb6 31.d5 Qxe3+ 32.Rfxe3 cxd5 33.Rxa5. Fritz's 14th choice was: (.95) (21 ply) 29.Qd2 Rxb6 30.cxb6 Qxb6 31.Rfe3. Pillsbury's move 31.Rf1 allowed 31...Rxd4 32.Rxa5, and now Chigorin could have played: (.32) (17 ply) 32...Qxa5 33.Qxd4 Qxa2 34. Ra1 Qd5 35.Qxd5 cxd5 36.Ra8. Instead, Chigorin erred: (.96) (17 ply) 32...c5? 33.Ra8 Qc6. At move 33, Chigorin slipped again with 33...Kf8?: (1.30) (18 ply) 34.Rc1 Rd5; or (1.23) (18 ply) 34.Rc8 Rd5; or (1.19) (18 ply) 34.Qa3 Ke7. I did not find a winning continuation for White at move 34. Additional analysis would be required to determine if White can win or if the position is a draw. Instead of the moves favored by Fritz, Pillsbury played 34.Qh3. The tournament book noted the natural looking move 40.Rb1? was a fatal mistake, and recommended the move 40.Qh6. After 40.Qh6 Fritz indicated: (.45) (17 ply) 40...Qd3 41.Rc1. As noted by calli, Pillsbury certainly could have had a draw in this position. |

 | | tamar: <Straclonoor> How can white win if Black does nothing? I don't see how. I investigated the position when you posted Feb09, and both SF and Komodo 10 get static evals, just above 2.00, but static. |
|
| Feb-10-17 | | Straclonoor: <tamar> In final position Black King cut off in 8th line and White can move King to Rook attack black pawns.
I don't see easy win too but let's wait for more powerful versions of Stockfisch.
Offtopic: Before computer era, this game was my favorite Chigorin's game |

| | tamar: This game is kind of a cousin of the game these played in Nuremburg Pillsbury vs Chigorin, 1896 Pillsbury finally converted the exchange up, and Chigoin hesitates a couple of time letting the knight live on d6 before snapping it off when it reached b6. I think Chigorin's game was barely good enough to draw, and to improve Pillsbury's play you might have to not exchange the bishop for knight on move 17. |

 | | NM JRousselle: 40 Qh6 getting the queen back into play looks like the right path toward stopping the c pawn. |
