Flop
Bet 30%of pot,and wait.If they will go fold,or check,you win.How?
1.If they will fold,you win.
2.If they will call,that means they have a small 9 or J of spade,or a pair and they are hoping to see the spade or t hit the set on turn.even like that you go all in after their call ,because you have a pair already ,and chances to hit the set or flush wich will make you win,and they will fold,thinking that you have the ace or king of spade(bigger spade).Anyway,sometimes there are idiots who's gonna go all after your raise in with a small pair,or small spade like:4 or 6,or they can try to bluf .So in this case you will have to go all in pay attention on your opponents play on the table from the hands before.
I hope this will help you on future.
