Sep-25-11  Patriot: I made quite a few mistakes here but I tried. It is interesting that I got the main variation (C.1) but a lot was off the mark.

This was more of an exercise in visualization for me because I wouldn't be able to calculate much of this OTB in any time control. So there was nothing realistic about my thought process on this one!

Sep-25-11  vonstolzing: Hello!
Best wishes from Buenos Aires!
For me this game was not a puzzle, because I'm a fan of Lasker.One of the latest gems of the genius. I believe that Lasker didn'd calculate all of the variants, like he did against Pillsbury in Petersburg.
Sep-25-11  CHESSTTCAMPS: Following is a link to the puzzle position using Crafty Endgame Trainer:

Crafty went straight into the C.2 line of my original post and puts up a tough defense, but I managed to win on the first attempt. Enjoy!

Sep-25-11  gofer: I would suggest the first two moves are quite easy to spot, but finding all the knight, bishop, rook and queen attacking combinations afterwards does may this a little tricky...

<13 Rxf6 gxf6>
<14 Qh5+ ...>

14 ... Kd7 15 Qf7+ Be7 (Kd8 Nxe6+ winning) 16 Nf5! Re8 17 Nxd6!! Kxd6 18 Qxe8 winning

14 ... Ke7 15 Nf5+! exf5 (Kd7 Qf7+ transposes to the line above) 16 Nd5+ Kd7 (Kd8 Bb6+ mating) 17 Qf7+ Kc6 18 Qc7+ Kb5 19 Qb6+ Ka4 20 b3+ mating!

<14 ... Kd8>
<15 Qf7 Be7>
<16 Nf5! Re8>
<17 Bb6+ Kd7>
<18 Nxd6 Kxd6>
<19 Qxe8 Qc6>
<20 Rd1+ Ke5>
<21 Bd4+ Kd6>
<22 Bxf6+ Kc7>
<23 Qxe7+> winning

Sep-25-11  victinho: yesterday's puzzle were harder than today's.
Sep-25-11  MiCrooks: Jim: isn't the Queen trade already forced? i.e. Black has to play Qc5 to both block the check and protect the Bishop. King move the Bishop drops and Bc5 b4 drops the Bishop again.
Sep-25-11  stst: A long and tiring day, and this insane puzzle must also be a long process.... just give a few strokes before bed time:
13.RxN RxR
14.Qh5+ Kd8
15.Ne6+ QxN
16.Bb6+ Kd7
17.Rd1 Be7
18.Nd5 Qxe4
19.Qf7 Rf8
20.Nxf6+ Kc6
21.QxR BxQ
22.NxQ KxB
W is one piece down but got position and P advantage... Too tired to continue (have to get up very early tomorrow morning for work.) Bed time...

I saw the bishop going to c5 first, then the pawn move and lastly black's queen move. 24...Bc5 25 b4 Qd4.

Sep-25-11  M.Hassan: "Insane" White to play 13.?
White has a Knight for a Bishop which is considered equal. Knight on f6 can be taken with promising attacks to follow:

13.Rxf6 gxf6
14.Qh5+ Ke7
15.Nf5+ exf5
16.Nd5+ Kd7 <....Kd8 17.Bb6+ Kd7 18.Qf7+ Kc6 19.Qc7+ Kb5 20.a4++ and it is checkmate or Queen is lost>

17.Nb6+ Kc6
White is now ahead by a Queen vs a Rook

Game may continue a different line if
Queen moves to d8 after check

13.Rxf6 gxf6
14.Qh5+ Kd8
15.Qf7 Be7
16.Nf5 threatening mate on e7
and Black Queen is lost
Time to check

Sep-26-11  jackalope: Hi all - just another novice here. Saw 13. Rxf6 gxf6 14. Qh5+. Thought 14. ... Ke7, but found that was incorrect and in my silly hubris thought 14. ... Kd8 was a blunder. Though he lost, Pirc played some pretty inspired defense after 13.
Sep-26-11  jackalope: Thanks to <sevenseaman>, et al for the analysis. I've just recently renewed my interest in chess and am finding the resources (Kibitzers, game collections, etc.) extraordinary.

  al wazir: <Bluegrey>: Thanks, but I don't think 15...Bd7 is any improvement.
Sep-26-11  Beautiful.LMS: This was a beautiful combination by the great Lasker.

  perfidious: <parisattack: ....Has anyone done the math for a 32 piece tablebase vis-a-vis Moore's Law?>

Still working on the seven-piece tablebase-the 32 should be a month or so away now.

  FSR: This Lasker was strong like bull. At age 66, he was undefeated in this tournament, finishing just a half point out of first in this tournament, behind the joint winners Botvinnik and Flohr. Another crush: Lasker vs Capablanca, 1935.
Dec-09-18  Saniyat24: The famous Lasker-Pirc trap...!
Jun-06-23  Mathematicar: I have very little knowledge in the opening theory, but I feel that today this is considered basic theory. Their theory stopped at move 7-8 in some lines, exception being old timers; QGD, Slav Defense and Ruy Lopez. Today, games are so theoretical so the middlegame is a mix of opening knowledge exam and only then strategical ideas. It's a pitty.
Jun-06-23  Mathematicar: Moves 10th and 12th by Black are blunders. Today this is unimaginable even at 2000-2200 level.
Premium Chessgames Member
  perfidious: A near call in the modern epoch: Nunn vs A Sokolov, 1986.
Jun-07-23  Mathematicar: <perfidious> Wow, thanks for sharing this!
Premium Chessgames Member
  FSR: This Lasker kid was pretty good. Maybe Pirc should have tried his eponymous defense instead, but he didn't take it up until 1946.
Premium Chessgames Member
  HeMateMe: 20 moves, and it's over...
Jun-07-23  sudoplatov: Capablanca did improve on Pirc's performance. I'd guess that Capablanca did look at Lasker's play and gave it a few minutes study.
Premium Chessgames Member
  FSR: <sudoplatov> Capablanca lasted over thrice as long as Pirc before losing to Lasker in this tournament. Lasker vs Capablanca, 1935. Yay, Capablanca!
