What should happen if a player fails to arrive at a neutral venue and a substitute is not available?

In the situation where a player does not arrive at a neutral venue and a substitute cannot be found, the correct course of action is to wait for a maximum of 30 minutes before considering the match forfeited. This rule is in place to ensure fairness and provide a reasonable allowance for unforeseen circumstances that might prevent a player from arriving on time. The 30-minute waiting period allows for any legitimate delays, but after this period, if the player is still absent, the match can be forfeited, ensuring that the game can continue without excessive delays. This maintains the schedule of the tournament or event and respects the time of all participants involved.

The rationale behind waiting for this specific time frame rather than waiting indefinitely or continuing without the player is to balance the need for timely progress in the competition with accommodating possible unexpected delays.
