First Prize - Jean Haymann
A brilliant problem with exchange of function between the black
rooks. In each solution one rook enters the pin line and then
moves along it to interfer with the other one. The black bishop
and queen on c1 & h1 determine if the mating move by the king
will be to e4 or f4, and this necessitates the correct white
first move by the pawn. We have an interesting dual avoidance in
which the wrong move by WPf3 takes the arrival square of the
white king (obstructions). The movement once towards the black
king and once away from it (this appears in additional problems
in the award) is artistically entertaining.

Second Prize - Shaul Shamir & Jean
Haymann
The two white batteries are alternatively exploited for
the pin of the black queen and for the mate. The "Pelle
movement" is made after the capture of a white piece and
although it is used for flight square blocking the effect looks
convincing. There is of-course a full harmony between the
solutions with exchange of roles by WBb6 and WRg6 in guarding
c1. Good construction and thematic twin.

Third Prize -
Menachem Witztum
Great idea sometimes require drastic measures. In terms of
content this problem is no doubt the best in the tourney. The
pin-lines are created during the solution by both black & white;
there is exchange of roles by the two pairs of white pieces; the
check on the first move determines the placing of the white
piece; and finally, in the first move the king is moving towards
the queen just to see her moving away from him on the second
move. The drastic measures required by the author include the
use of three black rooks and a non-convincing twin, and both of
this caused the placing of this problem below the other two.

Forth Prize - Jean
Haymann
Looks simple at a brief glance but it has movement and harmony
of the kind I like (and thus its placement in the award is more
subjective). These elements include the movement of king - queen
compared to queen - king, the check by black once in the first
move and once in the second, and battery mates once direct
and once indirect. All this is done in a pleasant airy
construction.

Fifth Prize -
Menachem Witztum & Emanuel Navon
The evaluation of this problem was not simple. On the face-of-it
the idea can be executed without the pin of the white queen.
However, the use of the black battery, apart from preventing
cooks, introduces a depth since there is a need to carefully
chose between the two mate positions. In the first move black
interfers with a white piece, the rook and the bishop,
respectively, in each solution, to enable entry of the black
king to the required square and pinning the black piece along
the way. The move by the black king opens the battery and pins
the queen which mates by the required "Pelle movement".

1st HM - Shaul Shamir & Jean Haymann
Mutual interferences by the black queen and
rook: in each solution the piece moves into the pin line and
then moves along it to close the line of the other piece. The
movement towards and away from the black king is entertaining.
The reason that this problem was not placed higher is that the
royal battery is, to some extent, artificial. In the specific
matrix used here one can consider another battery that enables
the use of interference, as used by white's first move in the
second solution by the knight. I prefer such an element over the
capture of the black rook.

2nd HM - Emanuel
Navon
One of three problems showing interferences of two black bishops
and which are under the shadow of the predecessor by Tkachenko
(see at the end of the award). The main difference here is in
the 2nd move by black: the rook at b8 must move to enable the
mate and it must carefully chose between the two available
squares. One can criticize white's first move, but I think that
the interference each time by a different pieces (in the second
solution the interference is clean since white has the choice of
1...Bg5) is more interesting.

3rd HM - Emanuel
Navon
The second problem requiring a comparison to Tkachenko.
Here black is responsible for the interferences of the two
bishops, but the main difference is in white's first move. White
must interfere with BRh4: in the first solution d5 must be
guarded and in the second d4 must be kept guarded. One can
criticize the fact that 2.Qd5 both interferes with BBg8 and
blocks a flight square, but in light of the dual avoidance this
looks minor to me.

Menachem Witztum
The "Pelle Movement" in this problem is by white exploiting the
pin of the black piece pinning the queen. In the first solution
the pin line already exist on f file and in the second solution
it is created during the solution. While in general I like such
differences, here it is clear that the second solution is more
interesting.

5th HM - Menachem Witztum
The two kings and the pinned pieces are all moving in
this problem. The "Pelle Movement" is exploited for taking a
flight square and there is a differentiation between the moves
of the white king in the two solutions stemming from the
position of the black pieces making this movement. In each
solution the non-pinning white piece moves to guard square
around the black king.

"Pelle Movements" are used here to block flight squares. The
queen moves into the thematic line and then moves along it. The
interferences of the black rooks, enabling their alternate

Zur
There are two solutions in each twin but the difference between
the two pairs is only in the moves by the white king. Still,
there is some interest in that in each solution the white king
is restricted to one square. In the first solution there is a
nice element: 1...Ke7? blocks the mating move by the pawn.
However, this element does not appear in the other solutions.

"Pelle Movement" for square blocking. In the second solution the
the moves 2.Bxe3 Kxe3 are forced to guard d3 compared to the
more freedom of choice in the first solution. There is of-course
interest in the fact that BRa4 prevent cooks by using a thematic
royal battery, but this is relatively minor.

need to find the way to obtain a free sqaure for the mating

Anticipations:
I actually found an almost full anticipation to only one problem
(unusual in a H#2 tourney), the same one mentioned in the award
for the 2nd and 3rd HM's. Problem #7 (Han) differs only by that
a white pawn makes the interferences of each of the bishop, and
this is not enough. |
