Source would be much appreciated, seems the Bishop-sac indeed works as third move only, yet for a study I'd admire the "reality- nearness"

This one is tricky indeed

Source would be much appreciated

I was talking about this one:

from here

http://www.talkchess.com/forum/viewtopi ... 36&t=59727

But forget about what I said, if it's a study, it's not as great as I thought, there yet would be a Major Dual with 2.Bxd6 working as well as 2.a5

Nevermind, I still like it, don't care too much about Duals for myself, it's just a matter of traditions and arbitrating somehow
