No.643 by Juraj Lörinc – Original usage of two Imitators with AUW! (JV)

Definition:

Imitator(I): Every time a piece moves an Imitator (or a set of Imitators) moves simultaneously in an identical manner. An Imitator cannot move of itself. If an Imitator cannot imitate the move of a piece, the move is illegal. An Imitator may only pass through or enter an unoccupied square and cannot move off the board. (this version of the definition is proposed by Peter Harris after the one shown in the Forum’s post). Castling is imitated by decomposing into a King move followed by a Rook move.

Some originality is ensured by use of a pair of imitators instead of single one, also the form of set play and solution is not totally standard. (Author)

Very nice! Interesting and matching setplay and a nice AUW.

This is also C+ WinChloe:

The real play is unique even if promotions to Imitator are allowed.

3. I like it! First time I see a pair of imitators moving so gracefully.
