the most boring opening of all

It is not boring if White punishes black.

3...Bf5?? 4.cxd5 and Qb3 is almost 1-0...

Sorry Nf6

Once again, black should take care of cxd5-Qb3 idea which works with Nc3 and Nf3.

Black's play is bad but it is just to show what happens if black just develops "normally".

I think u don't have a clue of what is the slav, so next time u tell an opening is boring, choose something u know...

Thanks pouncin, those are really nice traps.

Really, a 2500+ played this game with Black? I should move to that country.

Yeah, it is strange.

Maybe names were reversed when input?

Thanks, IM poucin. Great stuff!

Truly boring would be

Again needs a bit of cooperation from black. Has option of 6...Nc6 7Qxp bd7 8Qb3 Rb8 called the "Glasgow kiss" variation.

Bf5 reminds me of this wonderful game:

And especially this one:

Brunello has a lecture on youtube about the second game:

These two games are in the "Glasgow Kiss" variation I mentioned, and covered in Avrukh's book on classical slav. Seems fully sound gambit. 

The line without e3 is different, and probably just bad for black.
