2-3 can work if you have a good SF ! ;)
i'm in B3 semifinal ! i dont want to risk :) if i use of 2-3 my rival will play R&G :) dont think so ?? :))))
Actually I think 2-3 can work against Look Inside if opponent's PG and SG drive more than pass. If only one of them likes more to pass (=has a good passing skill), then 2-3 defense is useless against LI.
