Hi all!

In response to Stefan Buecker's demand I publish two of my recent correspondent games played in that fascinating variation. Both were played in Bulgaria's Individual Correspondent Semi-final Championship (BG-SF152/2011).

1/2-1/2

Imho, these are two of the sharpest sub-variations of Portuguese that I find difficult to play as a second player.

I admit I never had chances for a win in these games because my opponents knew how to play this variation and one of them has more than 30 experience in correspondent chess. I doubt if these were OTB games that my opponents would have managed to cope with it..

In addition, I publish another one, from the same tournament, in which my opponent wasn't fully prepared and tried to sacrifice the d4-pawn for an attack against my long castling.

Regretfully, I never read Michiel Wind's analysis in Kaissiber and can't comment his writings. Though I hope I can help the 'Portuguese lovers' with these games somehow.
