What do you know about the player? Are they chat happy? If so is there a coorolation between their chat and the hands they have shown down so far? If they are paying attention, what do they think you are likely to do in the face of the all-in bet on that board, the way the hand has been played?
Really not enough information here to say. But by thinking about these questions you may have some idea as to what they are trying to get you to do. I forget who said it but, "Figure out what your opponent wants you to do and disappoint them."
