#1 What was the style of that player(maniac? rock? )

#2 What was your image(rock? weak tight? maniac? agressive?)

#3 What image he thought of you....

#4 or even, what image he thought you thought of him.

If he was a tricky player and you had a very loose-agressive image, it could very well be a bluff. However if hes a rock who loves to overbet, then easy fold.

I would look at 20-30 hands on the hand history just to answer these questions and then make a clever decision based on that. You have 30 seconds time bank, use it.

My guess would be he wanted to steal the pot on the flop(or he could also have had some sort of pocket pair, thinking he could protect it), he then checked because he got scared you had the jack, and he then decided to bluff at it seeing your weakness.



However i lack information. What limit was it?
