So intresting would be some engine engine results with this postion. First with Qg2 then with Bf4. It is a game play not tactical test postion. Because programs give Bf4 only 0.96 and Qg2 1.50 or more it will even increase for some moves and then drop because the postion becomes unclear. But the end result is of more importance then the first move ! I think keep on searching might give us a cleu on the problem chess programs have here. Maybe on how to detect unclear postions. Marc
