Introducing the Terrapin
The Terrapin is an approach for White in the Torre Attack after 1.d4 Nf6 2.Nf3 g6 3.Bg5 Bg7 4.Nbd2 and then 5.e4. It is slow and unambitious, but very easy to play. It has been used by young Grandmasters such as Ponomariov and Radjubov.
It can lead to some interesting unbalanced positions and isn't all that well known.
