I heard this mentioned in a d4 post. Anyone know what it is? It has my curiosity going ... thanks

1 d4 d5 2 c4 e6 3 Nc3 c5 4 cd5 and instead of the usual Tarrasch with 4 ... ed5 Black plays 4 ... cd4!? or ?! (I can't be sure, leads to a wild type of game that is fun to play, though maybe not against too good a player with white as white should be able to retain a nice advantage throughout.

Very interesting, thanks much!

I was looking around for some example, and found this one, anyone have any other interesting games?

I play the von Hennig Schara quite a lot, especially over the board against weaker players.  I've a couple of games going on on this site at present against stronger players that you may like to watch.

I've not seen the 5...Ne7 move that's in your example.  I normally play 5... Nc6 at this point.

Very interesting, Thanks Geoffb01

On Chessmaster, there is a nice game played by Alekhine as Black in this line.  He uses his edge in development to completely overwhelm his opponent.

Sounds like a good game to look at.

White can also play 5.Qa4+

That was the line Alekhine played against.  I actually ran this by Fritz and Fritz likes it a lot.  That's saying a lot about the gambit if Fritz thinks a gambit is equal.

Well if Fritz says it good ...

The most comprehensive source on the vonHennig-Schara gambit is the German magazine Kaissiber, issue 31. http://www.kaissiber.de/
