Kibitzer's Corner
Jan-21-04  ughaibu: This is the hippopotamus defense. Spassky resorted to eccentric defenses in several games in the later stages of this match.
Feb-29-04  Bears092: the hippo is very solid, especially against computers
Mar-01-04  drukenknight: No kidding. Did you ever see people do that as white? Plus against Petrosian, I mean come on. Go ahead and let's see Petrosian attack it. Against Tal it would certainly be taking your life in your hands.

Did you see the odd stuff at the end of Korchnoi/Karpov 1978. I guess it was a Pirc, just a space grabbing qp opening. THen he just gets messed up. Those games lots of times end badly, for white or black, like you make one false move w/ your K and suddenly the other guys N is forking everything in sight.

Mar-01-04  Dick Brain: A site about this opening is
Mar-01-04  InspiredByMorphy: This game is so passive its mind numbing.
Nov-20-05  aw1988: Passive isn't a terrible thing. A lot of players, going through chess books, will mistake 'passive' for 'bad', unless the author means bad, which in that case it's very confusing. No, passive is waiting for something to happen.
Apr-05-08  Knight13: <This game is so passive its mind numbing.> Just both players playing very defensive games, or how about both players unable to find a way to crack the game open due to very solid iron walls?

<28. Bxg8> Afraid of ...Nf6-h5-f4 I bet. That'd put pressure in White's position.

Aug-16-19  RookFile: What strikes me is that black refused to take the lovely knight on d5, i.e. Bxd5. He realized that he didn't need to, and if he did, it would open inroads to black's position. Excellent judgement by Spassky.
