In the comparable Scotch line with the c-pawn back on c2 (1.e4 e5 2.Nf3 Nc6 3.Nc3 Nf6 4.d4), this move is risky - white continues with 5.Nxe5 Nxe4 6.Qg4! Nxc3 7.Qxg7, after which he should have the advantage. All moves by the c3 knight are met by 8.c3.... However, put the c-pawn back on c4 and white no longer has this resource! After 1.c4 Nf6 2.Nc3 e6 3.e4 e5 4.Nf3 Nc6 5.d4 Bb4!? 6.Nxe5 Nxe4!, then, white's best is probably 7.Qf3, with chances for both sides.<br /><br />The few GMs to face this e5 idea seem to favor playing more quietly with 4.Nf3 Nc6 5.Be2. I get the feeling that white's space advantage will leave him with the preferable game, as d4 is not the easiest square for black to control. On the plus side it's a fresh position with a lot to discover.<br /><br />If white, like black, is in an inventive mood, he could try 4.f4!?, in Vienna style, when the pawn on c4 hopes to be part of a large pawn mass and prevents black from countering with d5.<br /><br />Trevor MagnessTrevorhttps://www.blogger.com/profile/09820849350679462053noreply@blogger.comtag:blogger.com,1999:blog-2097781840059992476.post-2566075530799751932011-04-05T09:53:11.266-05:002011-04-05T09:53:11.266-05:00But what does White do with the extra tempo?

Though it's probably not the best line, White probably can fight for an advantage up a tempo.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2097781840059992476.post-39127327241288276772011-04-03T21:09:02.941-05:002011-04-03T21:09:02.941-05:00Yes.Yes.Frederick Rhinehttps://www.blogger.com/profile/11728232939607408071noreply@blogger.comtag:blogger.com,1999:blog-2097781840059992476.post-37072812522770999782011-04-03T18:48:59.477-05:002011-04-03T18:48:59.477-05:00A memory expert I'm not!
