Hello Uberdeker, Only started looking at these lines last night, so was only expressing my impressions. In the English with f3, the line 5... Qh4+ 6g3 does not look so promising to be after either 6...B*N or 6...Qh5 7Bd2 followed then by Nh3 to f4. Whilst, I agree that 5...e5 looks playable, it is not the sort of position that attracted me to this opening. Will check out, the Bd3 line, completely new stuff to me. In the Uberdeker, if transpose to Nimzo with 4..Nf6 after 5 e3 d5 leads to positons from Botvinnik v Tal, discussed in book "Opening Preparation" amongst other places, think conclusion was black was ok. However, it seemed to me, position of Nc6, made it harder to play than other lines for black. From normal Nimzo move-order, would prefer to play the standard d5,c5 positions or those with b6 and d5 lines. Of, course such things are a matter of taste. If 4...d6 was intending 5g3 e5 6Bg2 maybe black as gained something compared to normal Bogo-Indian, delaying Nf6. Still looks a pretty sedate positon though. Also 5Bd2 looks pretty safe for white, if snore inducing. Personally, I am only looking at playing these type of openings, as black, in must win situations. Typically, against a significantly lower graded oppenent. So my attitude in suggesting 4Nf3, was to kill black's fun, not to find the objectively most dangerous line. Bye John S
