another rule questoin

[BrianSwa]

ok here is another question that came up.

let me set it up 1st one dude bet and another one folded and the other guy thought the hand was all over and showed a K in his hand on a Q high board. The dealer pointed out that there was still someone else in hand and he quickly retieved his hand and flipped back over the K.


then the player with the K bet $100 into the pot and the other player said I got you, I got Q3 and you cant beat 2 pair with a K in hand. Now the player with the K wasnt all in he still had a couple hundred back. The player that said they had Q3 pushed all in, I thought you couldnt say your hand unless the other player was all in?


the dude with the K folded and other player showed 8-t with the flush draw, can you say your cards even if you are lying?
