Lors du congrès des compositeurs qui s’est déroulé à Jurmala en Lettonie , pays du Grand Michael Tahl. L’étude de Mario Matous a été élue comme la meilleure étude de l’année 2007. Je reprends sur la demande du juge Yochanan Afek l’article tel qu’il me l’ a transmis.

1.Nf3+ Kh1 !
1.Kh3 2.Ng5+ Kg2 3.Bxc5+.
2.Bd4 !!
With a mate threat. This spectacular move cannot be replaced by 2.Bxc5 ? Qa4+ 3.Nd4 Qxd4+ ! 4.Bxd4 stalemate.
2...Qf7+ !
After 2...Qc7+ ? White’s material advantage decides, for example 3.Ne5 Qc8 (3...Qb8 4.Rb2 ! Qf8+ 5.Kg3 Qg7+ 6.Ng4 Qc7+ 7.Be5 Qh7 8.Rd2) 4.Kg3 Qg8+ 5.Ng4 Qb8+ 6.Kh3 Qb3+ 7.Rc3 Qb1 8.Nf2+ Kg1 9.Ne4+ cxd4 10.Rg3+ Kf1 11.Nd2+. Bad is 2...Qb8+ ? 3.Be5 Qf8+ 4.Ke3 Qh6+ 5.Kf2 c4 6.Ra2 Qb6+ 7.Bd4 Qb1 8.Ra1.
3.Ke3 !!
3.Kg3 ? Qg6+ costs the rook.
. 3...cxd4+ 4.Kf2 ! Qf4
Very bad is : 5.Re2 ? Qe3+ and other attacking rook moves lead to a perpetual check : 5.Ra2 ? Qc1 6.Kg3 !? (6.Ra8 Qc2+ 7.Kg3 Qg6+ 8.Kf2 Qc2+) 6...Qc7+ 7.Kf2 Qc1 or 5.Rc8 ? Qe3+ 6.Kg3 Qh6 7.Kf2 Qe3+ 8.Kg3 Qh6.
5.Rc6 !!
Reciprocal zugzwang, as the queen has surprisingly no good squares. Thus a pawn has to move and obstruct the important diagonal b1-h7 in two echo lines :
A) 5...d3 6.Rc8 !! Qh6 7.Rb8 ! wins.
B) 5...Qe3+ 6.Kg3
Another reciprocal zugzwang.
6...d3 7.Ra6 ! Qc1 8.Ra7 ! wins.
