Seriously, I know its a DON, but folding the A high straight because they may be looking for a house or they may have a flush draw is soooo weak!
The full hand history would help, but it would appear that skyee either limped p/f with the SB calling and you in BB checking, and then a min bet from some one post flop. OR there was a min-raise p/f, and the flop was checked by all. Either way, none of the play represents a big pocket pair which would have hit this board, so I think we can rule out set looking for house. As for two pair looking for set, still no strength representing two face cards, and they have only 4 outs, 3 if they hold a Q. Flush draw is possible, but not very well played if that is the case, real bad board to semi-bluff turn IMO and the bets too big to call.
I think there is a good chance that one of your opponents has a J and you'll split, but you got to shove.
I always think it is a sign of bad players when they hold onto some chips like skyee has, or when they just call when they are totally committed like travelgirl. You may not get a better chance to take them out, so just go for it.
Just my opinion, but, if you find yourself in an awkward spot spend time thinking about how the hand has played out and ignore the chat box. Not only are you wasting your decision time but you are giving away information regarding the strength of your hand.
Hope it helps.
