You win .... oh, wait, no you don't

[TexRef]

Playing with normal group of poker degenerates in home game. I was on a flush draw, along with 4th pair on the turn. On river I miss, but bluff anyway, trying to bet other player off a mediocre hand, but one that beats my lowly pair.

He tanks for a while and finally says, "I call." ... my instant response is, "You win." -- until he turns over BOTTOM pair. Then I say, "Oh, no, you don't." and flip up my pair of 8s to beat his 6s.

I never mucked my cards - had them in my hand the entire time - but my friend thought that it was unfair since I had said, "You win." and tried to take his last bet back.

I told him that I never folded or mucked and another friend said, "Cards play." As a gesture of fairness, I told him that I would post the situation here to see what people thought...

So?
