Wesley So checkmates in 13 with 13 chessmen on the board:
8/7R/3p1k2/3P1pp1/7p/1r3B1P/2r3P1/6K1 b - - bm Rb1+;
6Q1/pp2k3/2b1p3/2PpP3/3P4/5N2/8/2n3K1 w - - bm Qg5+;
8/5P1k/p2B3N/1p1P4/7N/6Pp/P4q1K/8 w - - bm Kxh3;
For some reason I get a blank page with fen markers. Are fen tags possible here?
13 chessmen on the board, 13 moves to meet his lord
