Well after quickly letting my computer analyse the position (I'm not nearly good enough to make decisions like this on my own ) it actually gives white a small advantage. Obviously this doesn't prove that much but it has potential I guess
The way I see it, without a computer to help me, is that the d5 square is poorly protected by black and seems to be e fine target for white's knight. How this would be sufficent compensation for a pawn I don't know but I'm no expert either
I was recently looking at the Max Lange variation of the Italian in Yasser Seirawan - Winning Chess Openings. Although this looks like a very interesting variation, for one line given below
Seirawan states that 'white has shed a pawn for a dangerous lead in development'. To my reckoning white has only gained one tempo. I've read elsewhere (chessmaster perhaps?) that a pawn is worth roughly three tempi so what could Seirawan mean? Is the Lange a sound opening?
