ok, I don't want this to turn into a Johnny Poker thing:
Was in Costa Rica last weekend and played in a $1-2 cash game. I had about $150 and got pocket Aces. I raised to $12 pre-flop. Dealer called and so did a guy two to his left. Flop came 5-7-9 off. Two to his left checked, I bet $35, dealer called and TTHL shoved for about $80. I called. Dealer then went all in for about $60 more ( I know I'm wrong about the amounts but I had everyone covered if I called ) I wanted no part of calling the dealer as I was SURE I ran into a set. My question is since I had already called the first all-in as well as the dealer, what would have happened if I did not call the dealer's all in? Everyone at the table seemed confused. I just wanted to call TTHL's all in and I thought that his bet would just be called back and it would be a three way race for the original pot. I ended up called the dealer and he mucked when I and TTHL both showed pocket aces to a nothing board.
I hope this makes at least 1% sense.
