? This allows Black a [i][b]huge[/i][/b] pawn wedge on the light squares.

?? And this incarcerates the rook, knight and light-squared bishop, as well as the dark-squared bishop. Black can now complete his development, and build a king-side attack, at leisure - effectively three minor pieces and a rook to the good!

Preparations complete; f2 looks an attractive target.

! 25 ... de2, if I am completely honest, passed me by until I was playing through the game afterwards! White is lost either way, but 25 ... de2? would let the imprisoned pieces back into the game, so I could argue that I was right to play to mate the king with my extra pairs of minor pieces and rooks.

And my reward is a sweet, efficient, attractive mate from a decentralising sideways queen slide.
