[edit] 4...exd4
Although I wrote the original text suggesting 5.c3 in response to 4...exd4, I'm not sure where I got that idea (maybe it was original research) and I don't think it's correct. After 5.c3 Black can play 5...Na5 and seems to get an acceptable position. I used MCO-14 as a source for some of the article and it doesn't recommend (or even mention) 5.c3, instead giving 4...exd4 5.Nxd4 d6 6.Nc3 Nf6 7.0-0 0-0 8.h3 Nxd4 9.Qxd4 c6 10.a4 with advantage to White (Spassky-Hort, Reykjavik 1977). Maybe this part should simply read something like "If Black abandons the center with 4...exd4 White gets an advantage in space" ? Quale 00:01, 24 July 2005 (UTC)
Huh, that is an interesting point. The 5.c3 line definitely didn't originate with you. The 5...dxc3? 6.Qd5! line is well-known (including a game in Chess Life a few months ago, where W managed to lose horribly after 6...Nh6! 7.Bxh6 0-0! 8.Bc1!? Nb4! 9.Qd1? c2 10.Qd4?? cxb1(Q) 11.0-0?! (11.Rxb1 Nc2+ winning the Q) Qxa1). Your 5...Na5!? is an interesting idea I've never seen before. Krakatoa 00:25, 24 July 2005 (UTC)
I edited the text as per your suggestion. Krakatoa 01:32, 24 July 2005 (UTC)
Thanks. 5...Na5 isn't my idea, Fritz 8 spit it out when I fed it 5.c3. Searching the games database that came with Fritz, it shows two games with 5...Na5, both Scotch Gambits. In the second game White plays 6.Bb5 which looks more promising to me than 6.Qxd4 as played in the first, but the large rating difference means that the outcome isn't necessarily significant in trying to evaluate the position.

Thanks, interesting games. It was impressive how Black smashed White in the first game. Black played terribly in the second. I wouldn't want to play 5.c3 in light of 5...Na5! I can see why Hort invited 5.c3 and Spassky didn't take him up on it. Krakatoa 03:25, 24 July 2005 (UTC)
I just looked this up in NCO instead of MCO-14 and found that Nunn et. al. cover both 5.c3 Na5 (=, they say) and 5.c3 dxc3? 6.Qd5 (big White advantage). Quale 16:31, 24 July 2005 (UTC)
