Excellent guesses, all. But not fishy enough! Except Felonious' last guess, all of your guesses make sense with the cards that are on the table! To think like a true fish, you must
avoid noticing the cards on the table. (It requires almost zen-like focus. )
And, OK, it wasn't fair to ask anybody to try to guess this, because it's completely unguessable. The cards & bets tell you nothing at all. (Except my preflop & flop bets which are normal.)
I had KK. He called me down with 44.
No, seriously.
My all-in overbet on the turn was a misclick. I was trying to decide between a bet of about $2.00 and a check, and somehow hit the slider while I was thinking. I was seriously pissed at myself, especially when he called.
But Mr. Big Fish, wow! How on earth can you call that with 44? Any 7, 8, 9, T, or J beats you, as well as the overpair I was representing with my first two bets. His only chance was that I was on AK I suppose.
He disappeared from the table before I could get his name into my fish book unfortunately.
