wtf?

This guy was new to the table so I had no real reads on him... The table in general had a fair few people who would call/raise with Ax or Kx... my question is could I put that guy on without a read?

Edit: Turns out he was really loose and often pushed his chips in with top or middle pair even without a great kicker (he lost a lot of money fast)

You have nothing and he beat you into the pot, easy fold.

Even if he has bottom pair your a dog.

Oh, I agree that it was an easy fold for me; had no reads at all and like I said, this table liked going in with Ax or Kx so it was likely that my outs were greatly reduced with the number of callers. I think now after getting a few reads I'd probably put him on the straight, a draw (flush or straight) or Q/J/106...
