I bet this almost everytime. If someone throws in an raise against me I must think it over. What kind of hands do he play? How many times do he see a flop? And from there I put him on certain hands and play thereby. Also, alot of players like to bet out when a scare card hits the board if they put you on something else than in this case, an A or K. Is villain capable of doing this? Alot of things leads to a decision so in the end, it all depends.
