After 1.Ng3, b3, Bg2, 0-0, then d4! (instead of d3 aiming for a KIA) is this a reveresed grunfeld? Does anyone play this? .. seems quite solid for white.
Sorry about the delay in this- Keene had this game as being played in 1958, but it is listed as a 1957 game in my database, so it was harder to find.
Keene considers this to be an excellent example of the reversed Gruenfeld in its purest form.
The Catalan is essentially a reversed Gruenfeld where the extra tempo allows white to get in the thematic c4 (...c5 reversed), but it can be a useful arrow in the quiver of a Reti/KIA player.
