"Guess I'll have to figure it out by trial and error."
Or you could simply not try to figure it out at all.
Why are you wasting your time looking a duff variation (3...d6?)
If some mudhead is going play that then it does not matter which way you
go the chances are you are going to win.
When you study an opening you look at the established mainline
and plausible alternatives. Try not to get bogged down in the junk
that you may see once every 10 years in a blitz game.
And anyway 4.dxe5 is against the spirit of Urusov. 4.Nf3 and 5.0-0
develop develop develop.
You come on here cluttering up my chess forum with Queens off after 6 moves.
God knows how many Masters you have spinning in their graves.
"But greenpawn, he will take the d-pawn 4....exd4 and hang on to it with 5...c5."
OK don't listen to me. Listen to Woodworm.
He's the only lad on here who has managed to beat Weyerstrass.
He had that position. Look and learn.
(OK boys I've sorted it, you can stop spinning).
