{Over the decades Constantin has been a difficult opponent for me. After our
first game in 1984 the personal score quickly became 3-1 (not counting the
draws) in his favour. An over-optimistic attempt at improving my result failed
and for many years the score was settled to 4-1. But recently things have
started flowing my way: it could be that the difference of age (7 years) has
finally started telling. After winning against Constantin in the last two
years' team championships I now finally levelled the score after a third of a
century.} 1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. Bg5 {I didn't quite expect the
