Don’t miss Quartz TT11:
Since 1996, Glasgow Chess was very poorly represented and our belief is that this genre has a lot of potential. So, we are launching a thematic tournament, Quartz TT11, for problems with Glasgow Chess rules.
The tourney has two sections: a) fairy problems; b) retro problems.
In both sections, combinations with other genres, fairy units, are allowed, but Vielväterstellung problems are not allowed.
Send problems in an unlimited number to our Director, Dinu-Ioan Nicula, e-mail: nicudin004@yahoo.com, up to July 1, 2018

The 1st prize of TT10 (PG 7 & #1, All-in Chess) is cooked:

1.b3 Bb2 2.Bxg7 Bd4 3.Bxa7 Bc5 4.Bxe7 Kxe7 5.Kd6 Kc5 6.Kb4 Be7 7.Kxb3+ Kb2 & 8.Kc1#

The move 6…Be7 can also be played 1 or 2 plies earlier.

This cook was found using the upcoming version of Jacobi which will support All-in Chess as a condition.

Good job, Francois! I know some good All-in-Chess problems waiting to be verified.

All-in Chess is now available in Jacobi v0.3. Remember that Jacobi is limited to help games. I tested
