With button's raise, you can probably discount your straight draw and your queen outs so you've got nothing but spades, and the 6[img]/images/graemlins/spade.gif[/img] and 2[img]/images/graemlins/spade.gif[/img] might even be tainted vs sets. Otherwise, most spades will work for you. So we're looking at 7-9 outs, 4:1 to call which isn't enough given you probably have 16-20% equity here. There's also a chance BB reraises and then you've just been conned into playing your draw unprofitably.

This decision is very close with implied odds working in your favor. You have to lead a spade river. The 5s probably work against you because they probably make you call with a losing straight (or best case scenario, it gets checked through and you win with no additional bets). I'm leaning towards fold on account of possible reraises on the turn. Closing the action, calling is good. You make up the small lack of pot odds with implied odds as long as you don't pay off a queen river (a 5 I don't know how to play... call if BB bets or fold if Button bets).
