Italian order
I learnt a trick the high price tonight at my local club.
I often played the Italian (1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 ) and never really realised that you should not play 4.Nc3 as this is punished by 4... Nxe4 which gives Black a sronghold in the center
I checked back my history and I played 7 games online and nobody had challenged me this way which is quite interesting
