In this clip there is a similarity with yours truly - note the Swedish swearing at the end!

Both clips are of Johanna'a dad (Mike's father-in-law) whilst he was practising at the local Stockholm 'course' prior to our visit last month. It paid off - he beat me convincingly!
He is also a very lovely man who, it has to be said, is a trifle eccentric - but he is a mathematics teacher!!!!
