Further push singular extension Extend for an extra half-ply in case the node is (probably) going to fail high. In this case the added overhead is limited. A novelity is the way this patch has been tested: Always in self-play but with a much longer TC to allow the singular extension to fully kick in and also (my impression) to have less noisy results.
