Obviously the speech behooves us to fold.

However, the playful raise, when should we look at repopping or playing postflop or whatever?

Also, the nervous UTG raise, should we perhaps cc and wait for a K high flop and give preasure or reraise PF or whatever.

Any thoughts?

I was thinking a little bit more why the speech is rarely if ever made before a bluff. It is likely because speeches correspond to a situation where bluffing is basically unadvisable. For example if you take up a bluff to try and push off a made flush that would be pointless. Because even if you could convince the player holding a flush that you had a better hand, maybe even a better flush it is still unlikely that they will fold because they rightly perceive their own hand as very strong. It would be an unreasonably tight player who would automatically lay down a king high flush just because the board is paired. And even I if had the stones to try and represent a full house against a made flush I would be shocked if someone actually showed that they laid down a flush. I may be a degenerate bluffer, but I am not stupid.

Also, as a corollary ask your self why a speech is never made when someone turns over top pair top kicker on a safe board. Because it would be silly. So one of the few places where you could pull off a bluff giving a speech would just be odd.

Therefore the speech almost always means the nuts.

But it is an interesting point. Next time I play I might make a speech and bluff into a made flush. At the very least when I turn over my 72 offsuit to the king high flush it can serve as an advertising play.
