Re: Fascinating imbalance
Trivial edge for black, despite material advantage for white.

Alternatively [castling rights can be intact for white].

Re: Fascinating imbalance
Well, I would have thought the Cochrane- Gambit imbalanced enough, if you take two pawns away from Black secondarily, the position rather gets more balanced again than it was before, doesn't it?Nordlandia wrote:1. e4 e5 2. Nf3 Nf6 3. Nxe5 d6. 4. Nxf7 Kxf7 | Remove bPa7 & bPh7.peter wrote:Hi Jon!

Removal of Pa7 & Ph7 do grant black some sort of compensation due to semi-open file for both rooks. Moderately offsetting two pawn deficit.

Of course the early Queen-tradeoff might not have been the most aggressive game for Black
