you're playing a rebuy tournament and you know that you're going to rebuy if you go bust so this is an easy call imo as played...first of all, an ace or 9 is pretty much a lock for you, and there's a decent chance that a king would win the pot as well, which means you are almost getting the right price even if it wasn't a rebuy tourney, and the fact that you can rebuy is even more incentive to call...if you're willing to go ahead and do the double rebuy and addon as a result of going broke then there's no decision here really, but if that's something you don't want to do, then maybe folding is the best option, since it will save you some real moneyin reality, if you were willing to go broke with this hand, you should have just moved in on the flop...it's unlikely he's led into you on the flop with a very strong hand, and you aren't a big underdog against many possible hands, so the best play here would have been to just shove on the flop if you were going to call an all-in on the turn anyway
