White: Sg4; Black: Kc4; Rh5; Bf4; Pe3, Ph6.
Variations (in real solution):
In the framework of the #2 theme, is the play above thematic? In other words,
is the move 1…Bg5 regarded as Correction?
Reply: Yes, it is a correction. One of the examples is of the same kind.
a) In the position:
White: Be3 Sd4; Black: Kb8 Rd5 – is the sequence 1.Bf4+ Ka7 2.Bd6 thematic?
Reply: This sequence is not thematic, since the first piece to be attacked
must become attacked (and/or unprotected if necessary) by the move of a piece
of the opposite camp. In the example above, the attack of Sd4 is caused by
the move of a friendly piece.
b) In the position:
White: Ba7 Sc4 Sd4; Black: Ka8 Rd5 – is the sequence 1…Kxa7 2.Sd6 thematic?
Reply: Yes, it is.
c) In the position:
White: Kh2 Qa4; Black: Bd8 Se3 – is 1.Qf4 Bc7 thematic?
Reply: No, it is not. 1…Bc7 renders 2.Qxd3 illegal, and so only one black
piece is attacked instead of the required two.
d) In the position:
White: Kh6 Se5 Pd7; Black: Ka1 Rd2 – is the play 1…Rd5 2.d8Q thematic? A
pawn has been moving but a queen is en-prise…
Reply: Yes, this is thematic.
