Poker ruling

A situation came up last night at our weekly tourney game. It was down to 3 handed and after the flop the action was checked to the dealer button, who raised. The small blind re raised all in and showed 2 pair before the dealer had a chance to concider the re raise. The SB did not do this on purpose and thought the raise had him covered. This left the dealer knowing they were way behind to the SB 2 pair.
The dealer folded and the small bind took the pot. Did we play the hand the right way. Or was the person who exposed his cards early hand dead?

If anything, it saved the dealer from losing more chips. It was stupid move by the SB and he/she could've won more chips. If you reveal your hand before everybody decides to call or fold, purposly or not, is still a live hand (unless it touches the muck cards pile). You played it right.

The guy in the SB was an idiot, didnt break the rules as such (as far as im aware), but he was ahead and should have waited for the call.
Just on a side note once the pot is awarded that it, end of discussion. All issues regarding the hand must be resolved BEFORE this happens never after.

Like a donk last night who had a perfect trap hand against me but messed it up by betting out of turn. I picked up AKs on the button and put in a good raise, flop 10 10 K , and instead of checking the donk with pocket tens jumped up and bet totally out of turn, instead of checking to the raiser (me) and setting a trap. He could just have told me his hand there and then, well i suppose it was worse when a KQ called his all-in.

Nope nothing illegal just simple stupidity. His opponent got to see his cards before making his decision to call or fold! Oh if only we all had such kind opponents!

Here's the wsop stand on this if you're interested:

Here's the thing with home games: Rules are fluid, and most of the time there aren't rules for things like this, so some people will shoot angles. But try this in a big-boy tournament, and you've got trouble. Here's the ruling from John Bastarache, assistant tournament director/floor person for the 2005 World Series of Poker:

"The WSOP rule for this is never under any circumstances will a hand be ruled dead. In this case, the player would be informed that if he put money into the pot after turning over his cards, he would receive a 10-minute penalty. If he did not put money in the pot, he would receive a warning that the next time he turned his cards over he would automatically receive a 10-minute penalty. Further, we have the discretion to inform the entire table they have all been warned and anyone who turns over his cards will have a 10-minute penalty.''
