Well if he has a small stack i may check him see if he is gonna bet strong he may if he has that Q if he bets you can then raise him all in see if he calls if not you still stole a few of his chips.

If you have more chips say you have 20,000 to his 2,000(this is not based on any odds ) just push him all in no need to risk all your chips what if he has pocket queens and then 4th street comes and 4 comes out then the river a Q comes out you just risked all your chips when u could have just made him risk his and he won on luck. (chances of that are very slim i know but i have seen stranger things )
