Needs some tuning

Even in aggressive mode the computer is lax.
Always pulls straights, full house, flush.
You have a queen high straight, it has king high.
Both have same pocket cards way to often or if you have pocket sixes, it has pocket sevens.
Never see computer hand when you win. Only if you lose.
