Fold pre
I was once told by a friend of mine, after making a decision with the logic "he either has this or he's bluffing", that if we have never seen the villain before /are "readless", then he has it. This is a pretty horrible board, there is a chance he's doing this with a small overpair to protect his hand, something like 77 perhaps. There are also a lot of big draw type hands, plus two pair combos etc that would rather just take the pot there. Even though in theory their range could be pretty wide, because we are readless, im good with saying that he has it and folding.
Pre is ok, I probably lean more towards 2800 now but I iz a cash playa innit. Fold and win the comp on the next hand, or get it in and make quads imo.
