New testsuite: King's Indian Mar del Plata

[Jeroen]

Hi all,

Inspired by Kotronias on the King's Indian, volume 3, Mar del Plata I, I have made a testsuite with 50 critical positions in this line. Although the lines are long (sometimes even over 20 moves), most pieces are still on the board and thus they should lead to interesting, enterprising and complicated play.

Enjoy testing!

Thanks a lot, Jeroen

[MikeGL]

Thanks a lot for this link.

This is one of my classic favorite a win by Kasparov.

But I don't mean to hijack this thread and post useless analysis with my weak hardware.

Took the game from chessgames. I analyzed this game, which was published in a chess column in a newspaper, around 1990's before Fritz 2 even hit the market and intel i486 was very expensive. Strangely, the opening name at chessgames on above link is different
King's Indian Defense: Orthodox Variation. Classical System Neo-Classsical Line

The above game would be game 44 to 46 of your posted PGN. Again, thanks for this KID Mar Del Plata file.

[BrendanJNorman]

Strangely, the opening name at chessgames on above link is different
King's Indian Defense: Orthodox Variation. Classical System Neo-Classsical Line

This is similar to how in the Ruy Lopez after 1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.0-0 Be7 6.Re1 b5 etc. some sources will call this the "Ruy Lopez, Morphy Defense" - while others will simply call it the "Main Line Ruy Lopez or Ruy Lopez Main Line or even simply Spanish Game"

The name as stated here is the equivalent of just saying KID Main Line because it literally is the Main Line - even though the Bayonet Attack even has had bouts of popularity over the years.

NOTE: I've noticed (and this may be related) that lower rated players tend to love citing long opening variation names - like "yeah, my favorite opening is the Sicilian Defense, Dragon Variation, Hazai Variation, Bronstein Gambit" (and I've even seen them start verbally reciting ALL the moves just in case the listener wasn't aware)

While stronger players in conversation will simply say "You know that Dragon line where you play h5, Rc5 and launch your queenside pawns?"

I think in the former case the lower rated guys are virtue signaling (in a way), while in the latter, the stronger players feel they have nothing to prove and are just trying to make the other side know which line they mean.

I've had students say to me "yeah man, I wanna work on the (insert weird opening name) this week" and I'm like "errr you'll have to explain what that is" and it turns out it's some well known opening.

Interesting nevertheless - don't worry too much about the opening names - just positions and ideas.

You are spot on. Actually I memorized the above K.I.D. game of Piket-Kasparov by heart because I was young at that time and electronic DB and engines were not yet that common around 1900's in a small province where I stay, so I kept on replaying the game and analyzing each line until I memorized the whole game. I showed the above game around 2003 to a good friend who was already an IM and he just whispered, "ah, Mar del Plata". Then he also mentioned Nd2 was actually stronger and more common than the text move Ne1 that was used by Piket.

-ps
Very easy to memorize that game of Kasparov because all moves were logical after the opening phase.

[Jeroen]

Thanks, Mike. Indeed a great game by Kasparov.

The variation played by Piket is covered with positions 23 and 24 in the PGN:

[d]r2q2k1/ppNb1r1p/3p1nnb/P2Pp3/1P2P3/5PB1/4B1P1/2RQNRK1 w - - 0 23

[d]r2q1bk1/Np1b1r1p/1B1p1nn1/P2Pp3/1P2Pp2/5Pp1/4B1PP/2RQNRK1 b - - 0 21

and this how the last fish and komodo played this last 24 position at blitz

[leavenfish]

Most interesting...one should give (I would think) VERY long thinking time in such a suite as the structure is already determined. Fast time controls would seem not as appropriate here.
One would think over a bunch of games an engine with a bit more positional 'understanding', would have an edge.

Great attacking game on the h-file !
