I have an anology - when in doubt, bowl first. Simply because if you can't figure out the pitch, chances are they can't either. And bowling first gives you the chance to take a good look at what the wicket is capable of, making the run-chase that much easier. It is also very likely that they will start off slow trying to assess the wicket, so if it is good for batting, we'll have the upper hand there.
Looking at this pitch, I'm going to follow that analogy. No visible cracks, not a lot of grass, looks dryish and doesn't seem to hold a lot of moisture. It is definately hard, cloud cover and grass around the square may aid swing. But is just a strip of shaved land really, not much in it for either side. The ball might not zip through a lot. I'd like to be a spinner on this, but at the same time looks simple to bash the ball around a bit too. So since I'm unsure, I'm going to do the sensible thing and let them bat first. Get the quicks to pitch it up initially, make them play and drive on an uncertain pitch, and see what we get. Should be a bit of swing, if we are lucky mabe some uneven bounce or maybe good lift, maybe some seam movement. See what we get for the first 5 overs or so, and change tactics from there. By the end we should have a nice understanding of the pitch, and considering we've done out homework on their bowlers, we should be able to chase quite well.
