As luck would have it, I had to endure Oppenheimer's chaffing for a full month ere it happened.

And then, no sooner out of jacket and circulation restored, than I started knuckle-rapping the information.
Further, I taught Oppenheimer the chess Adam Strang had played in Cho-Sen centuries agone.

It was different from Western chess, and yet could not but be fundamentally the same, tracing back to a common origin, probably India.

In place of our sixty-four squares there are eighty-one squares.
We have eight pawns on a side; they have nine; and though limited similarly, the principle of moving is different.
Also, in the Cho-Sen game, there are twenty pieces and pawns against our sixteen, and they are arrayed in three rows instead of two.

Thus, the nine pawns are in the front row; in the middle row are two pieces resembling our castles; and in the back row, midway, stands the king, flanked in order on either side by "gold money," "silver money," "knight," and "spear." It will be observed that in the Cho-Sen game there is no queen.
