The more and more I think about this I absolutely hate the push. How can we be sure a spade is good if it's not the 10 of spades? We could be at one out here. At best we probably have 9 outs. Possibly the 9 plus the remaining 10s in the case that another spade doesn't come out.

For instance if the turn is the 10 hearts and the river the 2 of spades how confident are we?
