1bgmxcn,


My guess is that the button had a pair of aces or kings. When you are holding Jack-Nine that reduces the combinations of someone having a set of jacks or nines. I would never worry about that. Would he raise with a pair of fours? That's a possibility, but I doubt it unless he is a very loose or tricky player. You need to go with what you think he had on the flop.


Furthermore, your $50 bet on the flop looked suspicious. That's why I put him on a big pair, and he finally pried himself away from it on the river.


Good Luck
