Dear friends, I’m sorry for the unstable work of JF during the last week of June! Some changes from the hoster’s side, moving to the new platform, the same way some work I have to do as part of my code is not compatible with the new requirements.
Now the half-year competition JF-2020/I is over, all awaiting problems published. Please, wait with your next sending until the new tournament will be announced not earlier than in the middle of July! I need some time for technical work to keep JF up and running.

ANATOLE F. IANOVCIC MT

ANATOLE F. IANOVCIC MT

The Romanian magazine Componist-Buletin Problemistic is announcing the Memorial Tournament dedicated to Anatole F. Ianovcic, in order to commemorate 35 years from his passing away.

The tourney is for direct problems with mate in 2 moves, containing at least one grasshopper and/or at least one nightrider (other fairy pieces/conditions are not allowed), showing the Ianovcic theme: in the initial position, two black pieces A and B are half-pinned; after the key, a white line-piece C (= Q, R, B, G, N) is pinned by B (it could be already pinned); in the thematic variation, A plays, self-pinning B and, due to a black interference, allows C to give mate with a Pelle move (a move on the pin-line).

Entries should be sent until November 1st 2020, at the tournament director Dinu-Ioan Nicula, e-mail: nicudin004@yahoo.com
