Wacky HU action, Lagtard vs Lagtard, river bluffraising

[DespotInExile]

How can this question be answered without knowing if Lagtard A has a showdownable hand like 88? It only makes sense to checkraise if you have a complete bluff, not if you have something to showdown.

The risk to bluff raising the river, particularly given the example you earlier gave, is that you will get re-reraised on a bluff, and you will fold a winner. Or you will call because of this risk, and you'll find yourself crushed/dead on the turn.

So if you have a showdownable hand against a Lagmonkey like this, check-call seems best.
