20. Rxf7!! Well, there you are being a experienced German master facing some Dutch kid. Actually Sebastian Siebrecht has a theory about this: in Germany weaker players try to stay as solid as possible, hoping that they aren't being killed too brutally - in the Netherlands the weaker guy throws all his pieces in the attack hoping for that one genious game. Actually White is simply a talented player in this case. 20... Nxf7 21. e5 Kxg7 22. Qxh7+ Kf8 23. Rf1 1-0
