Rxe7 Qxe7 3. Nd5 Nxd5 4. Bxe7 That is the idea, isn't it? But after (say) 4... Nxe7 5. Qxe7 Be6 6. Qxd6 Nc4 Black has a solid position, only a small material disadvantage, and prospects of counterplay. So it's a matter of fine positional judgement whether cashing in with 1. d6 is actually any better than maintaining the pressure with 1. Ne5. Simon
