The kid really did make a meal of that final hand. He could have won the pot on 3rd easily with a riase, but didnt as he was attempting to trap Laney who had represented Queens. On 4th he should have made a large bet, much bigger than the lousy 1/3 pot bet he did make. Despite laney having a straight flush draw he could not have played for a big bet. But the biggest mistake of all was not playing for table stakes, but thats the biggest fault in movie poker.
