Kibitzer's Corner
Nov-02-14  rhedrich: White's well-placed pawns beat Black's ill-placed rook. Amazing.
Nov-02-14  Jamboree: There is so much crazy deep tactics going on in this game that humans will likely never understand why many of the moves were played.

Several different times when black had a rook up for the pawns, he make peculiar decisions to NOT develop and NOT untangle himself.


Probably because there were insane 12-move-long combinations awaiting any of the obvious developing moves, which both computers saw, so they both went instead into what to us humans would have been irrelevant side lines.

  Check It Out: It's instructive how both sides kept their knights "talking" to each other through much of the game.
Nov-02-14  956043: Jonny is handicapped by the move 3...Be6?
Nov-02-14  FairyPromotion: Wonderful game! I kind of wish it was played between two humans, but still...

Many times I have seen people discuss the standard material values, like how bishops should be worth more than knights, or sometimes how a queen is better than two rooks, but I think the most underrated pieces on this system are pawns. Give me 4 pawns over a rook any day.

Oh, and let me use this opportunity to bring a wonderful finish to the attention of those who might have missed it. Here is a game that was previously GOTD with the same pun: Hector vs J Carstensen, 2003

Nov-02-14  Ratt Boy: <FairyPromotion>:
Thanks for pointing us to that other Jonny. The ending actuary made me laff out LOL.

  Penguincw: Thanks to <notyetagm> (and maybe others) for pointing out this game, and nominating it for <GOTD>. chessforum

Also notice how after 23...Qxc1, black is down a rook for 2 pawns, and after 41...Kxd7, it's <2> rooks for 3 pawns. Of course, white quickly regains it.

The last GOTD to feature a computer I believe is Stockfish vs Rybka, 2013 on July 15th, 2014.

Nov-02-14  goldenbear: I used to crush Chessmaster from time to time.
Nov-02-14  wind mind: This is why we can forget about it...
Nov-02-14  Ovy: It's just amazing for how many moves SF was playing rook down.
Nov-02-14  Rama: I have to admire 37. Kh2

  kevin86: White's outside pawn will win!
Jan-01-15  Nova: Sorry if it is obvious, but why doesn't Black play 21…c1=Q? Isn't that just winning?
Jan-23-15  Jeff253: Nova... if 21...c1Q then 22.Raxc1 Qxc1 23.Nac4! White is down a rook for a few moves, but should end up a pawn up and with an superior position.

E.g. 21...C1Q 22.Raxc1 Qxc1 23.Nac4 Qc2 24.Nd6 (not quite as accurate is 24.Qd7 Ne7 25.e4 Qxe4 26.Nd6 Qxd4 27.Nexf7 Nbc6 28.Re1 Rb8 29.Nxh8 ) 24...f6 (24...g6 creating an escape square for the king, 25.Nxc8 Qxc8 26.e4 , 24...Rb8? trying to keep the material advantage 25.e4! Qc7 26.Nd7+ ) 25.e4 fxe5 26.exd5 Nxd5 27.Qd7 Qc7 28.Qf5+ Nf6 29.Nxc8

Jul-19-16  Keyser Soze: For a human perspective, would be a Knightmare (literally) defending those center pawns advancing plus that unpleasant conected knights on black's camp, even with a "rook down" (actually a rook for 4 paws). So getting a very active position paid off.
