Puzzle 3 from a Chinese master game played in 1993.
1.C2+6 is the better move.
1. R6+5 is not as good because it allows the defence 1. ... R6-1
yielding an unclear position:
A) 1.R6+5 R6-1 2.P3+1 P5+1 3.R5.3 (3.R5+1 R2.7 4.C2+6 R6.7 5.C2.5 H7+5
6.R5+2 R-.5 7.R6.5 yields a drawish position, Answer 2) R6+5 4.H3+5 E7+5
5.P3+1 R2.8 6.C2.3 H5+6 7.P3+1 H6+8, Answer 1, Black has lost an
elephant but the active horse offers some compensation.
B) 1. R6+5 R6-1 2.C2.3 P5+1 3.R5+1 R2+2, Answer 3
After 1.C2+6 the position isn't totally clear either but Red's chances are
clearly better:
a) 1.C2+6 R6.8 2.C2.5 H7+5 3.R5.4 (My source suggests 3.H3+4 which is also
interesting, but I think 3.R5.4 is even stronger) 3. ... H5-7 (3. ... P5+1??
4.R4+6! K5+1 5.R6+8, Answer 4) 4.R4+5 E5-3 5.R6+5 and
Red's pieces are very active, Answer 5
b) 1.C2+6 A6+5 2.R6+5 K5.6 3.A6+5 P1+1 4.R5.6 P5+1 5.C2.5 R6-1 6.C5.7 Answer 6
c) 1.C2+6 A6+5 2.R6+5 K5.6 3.A6+5 E5-3 4.C2.5 R6-1 5.R5.6 R6.5 6.R+.5 H7+5
7.R6+3 H5-7 8.R6.7 E3+5 9.R7.9 Answer 7
d) 1.C2+6 H5-3 2.R6+6 R2-2 3.H3-5 (3.H3+5 R6-2 is quite complicated) A6+5
4.R6-1 Answer 8, Red has a pawn plus and very active pieces
e) 1.C2+6 H5-3 2.R6+6 H3-1 3.H3+5 E7+5 (3. ... A4+5 4.H5-4; 3. ... R6-2 4.R6+2)
4.R6.5 A6+5 5.R+.3 Answer 9
