Game so far: 1.e4 e6 2. d4 d5 3. Nd2 c5 4. Ngf3 Nf6 5. exd5 exd5 6. Bb5+ Bd7 7. Bxd7+ Nbxd7 8. O-O Be7 9. dxc5 Nxc5 10. Nb3 Nce4 11. Nfd4 O-O 12. Nf5 Re8

If we want to exchange our knight for the bishop, now is the time. We could decide that we prefer to keep our knight on its dominating square f5, but we should be aware that if we don't exchange now then Black will probably reply ...Bf8 to preserve the bishop.

In the chessgames.com database the position occurs 13 times. In 11 games White played 13.Nxe7+. The other two games, both from the year 1967, were Matulovic-Maric, which continued 13.Qf3, and Janosevic-Matulovic, which went 13.Be3. In both games Black replied 13...Bf8.

Let's also note that the move 13.f3 is dubious before we've protected the diagonal with our bishop. After the reply 13...Qb6+ we are forced to interpose a knight on d4 in a self-pinning manoeuvre, because 14.Kh1?? Nf2+ 15.Kg1? Nh3+ 16.Kh1 Qg1+ 17.Rxg1 Nf2# is the well-known Philidor mate.

Does anyone advocate not taking the "minor exchange" now with 13.Nxe7+?

Nxe7+ all the way.

After this we get to think a little harder.

Both Rxe7 and Qxe7 have been played in human games. Wonder what SF will choose!
