Brian [1d\]: r3 is probe
Adria [19k\]: what is probe?
Brian [1d\]: it makes opponent make a decision
Brian [1d\]: later in the game, black might want to respond to r3 in a different way
Brian [1d\]: for example, if black had a big wall around P6 area, maybe he can do something like s3 and try to kill white
Brian [1d\]: as it is now, he made the decision already, so white can play move like Q2 later
