What if on the second one ne5
The Cambridge Springs Defense.

Seeing as you won't be able to trick your opponent every game, I recommend that you do a little bit of research on the Minority Attack. I believe that it should fairly easy to get into a type of Carlsbad Structure(where this type of an attack is a key theme) from this opening. However I definetly wouldn't recommend playing this in a serious tournament one day after learning it as it can be fairly complicated.

you mean in the second diagram dxc4 bxc4 ne4 threatening the knight and the bishop although you win a pawn it is not such a big deal

The first position is the famous Cambridge Springs Trap. It works against players all the way up to the 1800s.
The second, as you pointed out, is just another example of White making a blunder.

What if on the second one ne5
works
You'll win a pawn
actually life isn't that easy because white has a mating threat in d8 after cleaning up the d-file. but yeah, after ..Nxe5 dxe5 Bb4 i guess i'd rather be black.
f6 Nxd7 is a trade - between taking on g5 or d7 and stuff this might be good for black too

dxc4 white should play Bxf6 - and even after Bxc4 Ne4 it can still be "saved" by Bh4 Nxc3 bxc3 Qxc3 Nd2. in that case life sucks for white though.
Hi all. I was just wodering about this opening and I know it has many traps, but I cant find a good video disscussing all the main traps, so can somebody post a diagram of the traps or post a link? Here's the first two I know. Oh and PS I need this for a tornament tommorrow.
