I have about 15,000. Blinds are 100/200.I look down at 99 and raise to 600 and get called by Player He has about 30,000.Flop comes 58JPlayer checks, I check (thinking he might want a check raise)Turn comes 58J(9)Player checks, I bet 4,000. Player raises me all in.Since i have made a set of 9's, I call. Player turns over JJ. A blank card comes on the river and he wins the pot.Do I suspect that he has jacks in the hole? Did I make a bad call when i went all-in or is just a bad beat i have to suck up and take.Thanks for the help guys
