Award Studies Problemaz 2008
MT Mohamed H.Bahaoui (22/10/1933- 19/07/2007)
By Harold van der Heijden
FIDE judge for endgame studies
26/09/2012, Deventer, the Netherlands
First I have to apologise to the composers and readers of Problemaz for my seriously delayed award. Unfortunately, the overall level of the tourney was low, with only a single study standing out, which however would probably not have won high distinction in a major tourney. A positive point is that all studies seem to be sound !
The following studies did not make it into the award :
#255 : 7.Bh2 !! is a nice move, but (in the lines provided to me) the composer manages to hide the subtle difference between 7.Bg3 ? and 7.Bh2 ! After 7.Bh2 ! Kc1 8.Kc3 Kd1 9.Kd3 the difference is that after 9...c5 10.Kc3 Ke2 the only drawing move is 11.Bg1 ! After7.Bg3 ? Kc1 8.Kc3 Kd1 9.Kd3 c5 10.Kc3 Ke2 the move 11.Bf2 is not possible.
#256 : Bristol manoeuvre where White has to chose the right combination of clearance move and retreat. Only 1.Bc3 and 2.Qd4 work, since both pieces have to deal with the dangerous d-pawn : the wQ has to guard the promotion square, while the wB must be able to capture the pawn at move 6. The rest of the study is hardly interesting, except for the bonus of the final stalemate.
#257 : Castling in studies is not so special any more : there are 390 studies present in my database in which White castles during the main line. Here White, being a full rook up, finds a way out of the double attack my building a battery by castling. The same idea was shown by Saetta e1d8 1952 (HhdbIV#25988).
#343 : The highlight of this study is the first move. Another example where the composer just selects the “longest” lines, rather than illustrating the tiny difference between key and (thematic) try. 1.Be4 ? Ba6 2.Kf6 (like the main line) fails to 2...Rf8+ cannot be met with 3.Bf7. Of course, then the main line should run : 1.Bd5 Ba6 2.Kf6 Rf8+ 3.Bf7, but also 3.Ke7 and 3.Kg6 win here. But that would hardly make it a study, wouldn’t it ? As a consequence, 1.Be4 ? is not a thematic try and the highlight of the study is lost.
#344 : Only obvious moves.
#440 : The composer calls 1.Sf6 ?/9.Sc3 thematic tries, but their refutations are rather different from the main solution. 3.Sg3+ gets two exclamation marks, but it is (almost) the only way to prevent a quick loss of that knight (Black threatens Kxh2-h3-h4). Although White has to avoid some pitfalls, the remaining moves are obvious.
#443 : The stalemate, also with a similar introduction and a rush of both kings, is known from Gorgiev a1e2 1975 (HHdbIV#42389) and Aliev d2a4 2003 (HHdbIV#70243).
