I don't think its the ideal board to slow play bottom set against a player that you have no information on also there are 5 cards that can come which could lead you to being pushed off the best hand if the
are good.
Any A K Q 8 or 7 and you have no idear where you are and its going to cost you the majority of your chips if not all to find out.
3k is quite a large bet for the person to lead out with against 1 opponent, slightly over the full size of the pot, AA,QQ or 88 are my main thoughts atm. (Doubt it is that tho, might be a little to predictable for a threadlike this)
Quite a small raise utg with AA for a guy that has just sat down at a table, I think most people would make it 4x or more the bb with AA in this situation, they don't know how the table is playing so they dont want to have 4 callers with AA utg against strangers.
I go with the raise up to 8k - 9k.
Nightmare decision...very unliky that he has KQ or Q8, looks more like QQ,JJ,1010 or the outside chance of 88.
Still not sure what I would do tho lol
Might go the catious route, If he has QQ or 88 fair play ballsy move but he still has a strong chance of winning the pot anyway, if he has the sets then you made a correct pass. If hes on a total bluff or has pocket aces then hes insane and you've got a good chance of getting the chips back off him, just hope no one else gets em first.
Glad it was'nt me!
