The reason Im asking is because a lot of the time people push here with a semibluff, and it will look like you are trying to make him fold. What are the chances another spade spikes on the turn/river?

im not sure if a push is optimal ,the pot is so small that folding is easy for him , and you'll make him fold hands that you want him to call with Js/Qs

there's a 24 percent chance another spade comes on turn/riv (thats assuming villain has a spade)
