Am I correctly interpreting (2) and (5) as saying that moving into check is legal but selecting a move into check is not legal?
What happens if only one player’s move is possible, such as if Black selects e8-f7 and White doesn’t attempt capture on f7 at all? Does this result in White’s move happening 100% of the time, or is there a 50% chance of no move?
What happens if both moves are possible but the resolution order matters? If White selects f3-f7 and Black selects d8-f6, this could be resolved as Qxf7 followed by Qf6, but it could also be resolved as Qf6 followed by Qxf6. Is one resolution order chosen at random, or is the first one “preferred” because White completes its full move? I’m seems like there could be a situation where both/neither moves can be completed fully but resolution order still matters.
You are correct by my reading. If you could not end up in Check, the game could not end by “capturing or checkmating the opponent’s king”. Therefore, (2) states that the check for Check is made given the “current board position” at the time of move selection.
By (5), a player choosing a move that could become legal but does not do so forfeits that move.
My question is similar to this, so I’ll tack it on here:
How are moves timed? Suppose there were no pawn at d7 in the first position. The moves are revealed as White:f3-f7, Black:c8-f5. Now, does the bishop block the queen and get captured at f5, or does the queen take the pawn and the bishop block retreat?
Possible solutions off the top of my head, ordered from least to most interesting:
There is a discrepancy. By rule (1.3), only one of the moves executes at random (not very satisfying)
Roll off to see which situation resolves
Moves resolve one space at a time. In this example, that results in the bishop being too far away to do anything about the queen
Both games are played out simultaneously (hard mode!)
Both possible outcomes resolve at the same time with the relevant pieces becoming entangled and in superposition (quantum chess)
Also, how is this game notated? “White:f3-f7, Black:c8-75” is a bit clunky, imo
