The answer is +R-83 and S*72 ,but you can also go P-83+,and if the bot go K-71 then you go S*72,or if the bot go K-81 then you go S*82 ,it is another aviliable answer,but when I do like this, I'm told to be wrong

@gary88 +Rx83 instead of K-71 after P-83+? That doesn’t allow a mate in 3

Notice the dragon on 89, if You go P83+ it would be taken by dragon.

In the third move, B*63 (K-82 Sx83+ Kx83 P*84 ...) also looks correct, but it does not pass.

Today's daily has the same problem I think. R-31+ Kx31 G*22 (or R-31+ K-12 B-22+) is valid too.
