Bc1 { A curious position: White's bishops have moved a combined total of five times, but it looks like they've only moved once between the pair. And yet, despite being four tempi down, White is better, with firm control of the center and pressure on Black's misplaced knight! } 11... Qa5 12. O-O Rd8 13.
