This is an important lesson in chess. Always check everything at least TWICE!

The above is a recent game of mine. I was White. After I played 16. Nxd5, my opponent resigned. He thought he would lose a piece because of the pin on the c file.

However, if he would have checked twice, he would have realized that
16… Nxd5 17. Nc4 Bxd4 18. Qxd4 with a small edge for White.
(if 17. Bxd5 Bxd4 = or if 17. Bxe5 Qxe5 18. Nc4 Qe6 +=)

Even though White retains a small advantage, it is hardly a resignable position. So be sure to double check all lines in chess. Good luck!Posted by Picasa
