I noticed one player in round 7 using a blue hand held device for recording of his moves, and not using the pen/paper at all. What gives - is this a new trend for move entry? And how to cope when all players are using them? Maybe you did not notice this, but surely one rule for all would be the principle. I am assuming he transcribed the moves back to paper before handing it in.
Yes, I did notice it and the player in question was Amir Karibasic of the Kings of Chess club up in the Gold Coast. He used the device for every single one of his games. The device is actually a Monroi PCM. Before anyone gets all excited, this device is FIDE approved and is, in fact, used in a number of tournaments around the world including the US Champs and the big Gibraltar Open.
It's actually been around for a few years now and will be used in the Oceania Zonal later this year.
After each game, Amir's results were validated by an arbiter (the arbiter affixes his signature digitally) and in case of disputes, the arbiters always relied on the opponent's paper scoresheets.
