2 checkers left back game

Here is a back game where bot(playing white) had 2 checkers left to bear off. It rolled 5-2 which forced it to leave 2 blots which got hit. And after multiple attempts at trying to come back around and getting sent back, we ended up with a redouble to 4 which it took and lost woo hooo :D (download the sgf file (backgame9_2015.zip) to see the whole match in gnubg) rating for the match was "advanced" which is pretty good for a back game as it usually has many errors. The double was good no double at that point would have been a blunder. So basically u don't want the opponent anchored when you have his 2 checkers sent back. You want them both on the bar. I tried to lure him out but he didn't roll any sixes so I had to bring all my pieces in but it worked out anyway I got enough of my checkers off before he scampered both out and I was able to redouble and win the race. So the plan is to either block big numbers like 66 55 or distribute your checkers so that you get maximum chances to hit any escaping checkers.

Have you ever seen it make a wrong play?
If it plays perfectly on almost every move, why would it need to cheat?

I know for a fact greedygammon doesn't cheat because I wrote the part that generates the rolls.
It picks 2 random numbers. That's it. It doesn't look at the position to see what roll is good or not.
Well, actually that is not true hahaha :D
Greedygammon DOES CHEAT!
If your rating is below 1750 it will give YOU a bunch of lucky rolls.
So it cheats AGAINST the bot.
You can turn off this feature if you don't like it.
Most players would never even know it is cheating for them.
They are just happy to win more games.
