Hello,

I would to work this kind of position :

So to learn how to build an attack on the kingside playing Qh4.

Do you know, please, how to set this kind of position in chessbase to find games looking this one ?

With Chessbase 11?

I have chessbaselight premium

you can search for the position, but it will only give you exact matches for that.  If instead you put in only those pieces (using "set up board" from a blank board) critical, and the essential pawn structure, you should get relevant results.

I would try putting in only the Kings, Rooks on f-file, Ne5, Nf6, Bb7, Bd3, Qe1, and the pawns on the d-h files, maybe including Black's a6 and White's c3 if the return is too many.

Thanks, it is good clues. Looks better putting adding a queen on h4 or g3.
