Can anyone explain why Re7 is one of the lines suggested by the computer? I was analyzing a game and got stuck in this position by Re7 move. I do not want to mention the player's name. As seen in the diagram Bc5 is misleading, but Bd6 is one of the lines. Bd6 is OK, but Re7 seems inexplicable to me. Please anyone can explain??
Protecting bishop for case Ne4 Nxe4 dxe4 and having f7 covered is also useful. Calm position, no need to hurry.
