Giday I had a ruling to make the other week & would like to hear from other professors, how they would've handled it. It was during the 8th round of 10, with both players currently in the top 8 standings. I had a young player (approx 7 years old), that is above average in skill, call me over for a ruling. His opponent was another player of approx the same level, but alot older (approx 14). His problem was in his opinion, the older player had removed damage counters from his benched pokemon & not put enough on the active, in order to hide from his Baltoy attack. Upon trying to ascertain the damage that had been dealt out, it appeared the problem may have started 4 or 5 turns earlier. Both players put up strong points when asked for their version (both possible for thier skill levels on why things were done during turns). Obviously, it came down to a he said & they said situation. Due to it being impossible to reverse the situation back that far, i ruled that the game continue in the state it was currently in, as both players had made descisions based on the game state at the time of their turns. I also explained & recieved confirmation from the young player he understood why i needed to be called earlier & for him to pay more attention to what the opponents were doing. As you can imagine, tears resulted from the younger player, which took a few minutes of calming to allow play to continue. It ended up being a draw after the time extension. 2 rounds later, this exact same situation then came up with the same young player against one of our top ranked players (now World #1 unlimited POP ranked player) . On this occasion, it again had been 4 or 5 turns go by before i was called. This time, i ruled that it was highly unlikely that the opponent would do the same thing & gave the young player a Match Loss for unsporting behaviour, due to it being the last round. I then explained what had happened to his parents, so they knew what had happened. I've never seen him back to any of our weekly tournaments since.
