5th Japanese Sake Tourney
Judges: Tadashi Wakashima, Kohey Yamada,
Yuji Kikuta & Hitoshi Yanami

Crazyhouse. #n, H#n, S#n, SH#n, Proof Games, or whatever.
No other fairy conditions or pieces are allowed.

Crazyhouse is a chess variant often played on the Internet. When a piece is captured, it changes colour, and is kept as a pocket piece. A player may drop a pocket piece instead of a normal move. A pawn may not be dropped on the 1st and 8th rank. When captured, a promoted piece is kept in hand as a pawn. In a problem using Crazyhouse, you can indicate pocket pieces, if necessary.

You can participate with either of the two following ways:

  1. Send your entries via e-mail to Tadashi Wakashima by the end of August at the latest.
  2. Hand over your compositions to any of the Japanese participants during the congress by Wednesday night, 8th of September, 9.00 PM.

The original announcement is on this page.

1.Lxd5 Sxd6 2.L@e3 S@b5#
1.Sxc4 Lxf3 2.S@c3 L@c5#

Note: "@" indicates a pocket piece "drop"

In the first solution, the white bishop and the black knight are captured, so they change colour and become pocket pieces, which can drop later.

In the second, the white knight and the black bishop are captured, so they change colour and become pocket pieces, which can drop later.

  HS#3½ b) Sc2=>h4
PG in 15.0

1st Prize: Vlaicu Crisan & Ion Murarasu (Romania)
a) 1...Se3 2.Sxe1 Dxe1 3.S@h4! (3.S@f4?) S@b4! (S@f4?) and now 4.Dg2+ Sxg2#
b) 1...Sf3 2.Sxg2 Dxg2 3.S@c2! (3.S@d3?) S@g6! (S@d3?) and now 4.De1+ Sxe1#
A perfect orthogonal-diagonal transformation. Particularly fine point is that Sc2/Sh4 in the twin (a)/(b) reappears as a dropped piece in (b)/(a).

2nd Prize: Michel Caillaud (France)
1.b4 a5 2.bxa5 Txa5 3.P@a7 Te5 4.a8=L d5 5.Lxb7 Kd7 6.P@a7 Ke6 7.a8=S Kf5 8.Sxc7 Le6 9.P@d7 Dc8 10.d8=T g6 11.Txd5 Lg7 12.P@d7 Lf6 13.d8=D Sd7 14.Dxe7 Sf8 15.P@b2 P@d7
AUW. A light-weightier for Michel, but charming nonetheless.

wP in pocket

1st Honourable Mention: Emil Klemanič (Slovakia)
Set play: 1...Sexc4 2.Td3+ S@d4 3.Lf7#, 1...Sxg4 2.Lf7+ D@e6 3.Td3#
Solution: 1.Kf5! (2.Sxd2 ~ 3.S@c7 or 3.S@e7#)
1...Sexc4 2.Lf7+ S@e6 3.Td3#, 1...Sxg4 2.Td3+ D@d4 3.Lf7#
Reciprocal changes between set and post-key play. The construction is flawless.

2nd Honourable Mention: Paul Raican (Romania)
a) 1.P@b3 Tb8 2.Df8 Txb4+ 3.axb4 S@a4 and now 4.T@e2+ Lxe2#
b) 1.P@f5 Lxb4 2.axb4 S@c6 3.L@d3 Tc8 and now 4.Dd4+ Sxd4#
The solution of (b) is very hard to find. A miraculous gem.

1st Commendation: Michel Caillaud (France)
1.Lg6! fxg6 2.d8=D+! L@d7 3.Tf5! gxf5 4.Db8+ T@c7 5.Se4+ fxe4 6.D8b4+ S@c5 7.Dd3+ exd3 8.Dd4+ D@d5 9.De5+ Dxe5#
Attractive play with dropping DTLS. It is a pity that only D and L are utilized in the mating position.

2nd Commendation: Jim Grevatt & Tony Lewis (Great Britain)
1.Tb3! (2.Lxe4+ Kxe4 3.S@f6#)
1...Tc6 2.bxc6 Kxc6/d3 3.T@c5/3.T@d6#
1...d3 2.Txd3+ Td4 3.P@c4#
1...Tc3 2.Txc3 dxc3 3.T@d6#
4 (actually 3) pin-mates. Simple and elegant.

3rd Commendation: Aleksandr Miholap (Belarus)
1.Tf6! (zz)
1...gxf6 2.Dxf6+ T@e5 3.Se2+ fxe2#
1...gxf4 2.Txf4+ S@e4 3.P@c2 bxc2#
A well-matched pair of variations.
