ToP says that a raise is the right defense against the semibluff most of the time, but that one exception is when the semibluffer is on the come.

Going by recollection only, it seems like almost half of semibluffs online are on the come.

So has the exception become the rule?

Also consider: another exception mentioned is when the pot is large enough to make a raise ineffective -- i.e. the semibluffer will not give up the pot. Especially in limit games, this seems to be the case a great many times.

This implies that passivity is not as bad as we initially thought? Discuss.
