Jan-21-04  ughaibu: Hippopotamus attack!?
Jan-21-04  Benjamin Lau: Lol. ;-) (Hippopotamus Defense according to one source (1. e4 g6 2. d4 Bg7 3. Nf3 d6 4. Be2 e6 5. c3 Nd7. 6. o-o Ne7) I guess the Hippo Defense is basically the Reti system reversed?
Jan-21-04  Whitehat1963: Why on earth is it called that?
Jan-21-04  ughaibu: It's so called due to an imagined resemblence between the pawn structure and a hippo emerging from the water. It's been played at least once in a world championship match, I'll look out the game.
Jan-21-04  Benjamin Lau: Petrosian vs Spassky, 1966

Here, I had it in my game collection under "Miscellaneous." I was amused Spassky would be willing to play it.

  Honza Cervenka: 36.g5 Bc3 37.Qh6+ Kf7 (37...Kg8 38.Nxe6) 38.g6+ would have won the game quicklier. Black could have resisted a little bit longer playing 39...Ke7. In final position after 42...Bxg7 white gives a mate in 2 (43.Rf7+ Ke6 44.Qe8#).
Jul-27-17  BwanaVa: In "Flank Openings", Raymond Keene annotates 24. Ng4 with "Lein wakes up!", and describes the systematic "peeling back" of black's defenses.
