For the last 2 weeks we have at last been able to play chess normally. My tuition this week began with an introduction to the very dangerous Vienna opening where on move 2 after 1.e4 White plays 2.Nc3 rather than the more common 2.Nf3. Over the coming weeks I will be exploring the main lines of this opening in more detail which in my opinion is worth playing up to about ECF 180 or FIDE 2150. During lockdown I beat a 200 plus graded player with it so it is definitely worth looking at.
