我后G5不就赢了吗？为啥不让我这么走？ 

Nice 

bittiiiii 

I made a wrong move before it made sense. One wrong move and it's hard to dig myself out of a bad idea. 

Brutal! I gave up several days in a row. Also even though mate in 3 is possible(?), the game won't accept anything other than mate in 4. 

Mate in 4. It's pretty deep - I admit I didn't anticipate black's responses. The solution is satisfying as a chain-reaction. 

 

 

There are 2 viable solutions (the 2nd move has 2 options), but the game insists on one of them, and rejects the other. Frustrating. 

This was fun when it finally hit me: "Slap!"
