Jackson V Ivy...How did Ivy make this bluff?

[Karel]

I have never seen as many bluffs into one pot before, it was incredible double bluffing, but Phil Ivey came out on top. He obviously had very strong instincts, did Paul do anything wrong?

My theorys are that Phil Ivy would have thought Paul would not raise with a jack in his hand. But maybe what he picked up on was Paul's last raise and that he saved himself some chips and did not go all in. Phil maybe thought that he has saved himself some chips if it goes wrong and therefore looks like a bluff.

Whatever he picked up on it was classic Phil Ivy.
