Thanks Peter.
I will follow your statement as the right viewpoint in this issue. However I wonder why the preset's program did not prohibit that double capture if it has reinforced the rules.
I made these two moves to test the preset:
1) C h5-f7;f7-h7 by capturing two pawns (f7 and h7)
2) C h5-f7;f7-h9 trying to capture the g8-advancer after capturing the f7-pawn
The preset's program allowed the first and banned the second.
Perhaps Antoine Fourrière may have something to say since he was who reinforced the rules.
