Juanda Crippled

Juanda raised pre-flop to 650, he is called by unknown player, The board comes Kh Jh 8s, it is checked to john who bets 1350, he in turn is called. Then the Qd appears, Small blind then fires out with 2000, John thinks and then calls, River 4c changes nothing. John has to then call 3100 more to see the 10s 9s that takes a good pot from him. John still has 19K in front of him.
