Same game - How many bets max can it be correct to go with a pure bluff on the river?

the first player bets.

The second player's action vector looks like this.

|______________call_______________|________fold___ ___|

When should the second player raise?

|_____raise___|_____call___________|___fold_______ __|br|

This pure bluff raise looks spectacular when it works.
But the math says never bluff raise from the fold area.

|____raise____|____call_________|br|________fold__ _____|

The bluff raise from the tail end of the call area does
better.

If that's what you meant by pure bluff, never pure bluff.
