proud of my 66 PR

In Response To: Cut Phil some slack... (Casper Van der Tak)

Cutting me some slack is always a good idea! However,

First, xgr+ had me at 66 PR that game but ++ said 56, so I wasn't that bad after all.

Second, I won that game. If XG was playing my side I doubt it would have won.

Third, I sent that game to several of the best players in the world and they agreed that XG does not have a clue here.

Jim Pasko, perhaps the greatest back game player of all time, is willing to prop it against XG. He will play both sides a number of games and end up with more wins from both sides than XG gets. He is also happy to prop the cube against anyone.

When my opponent, Vadim got down to three checkers he passed this cube...however in his defense he was leading 2away/6away. For money, xg says this is a beaver.

This is another example of XG not understanding positions like this. Again, Pasko will play anyone who wants to take this cube for money. I would not do that myself, as I think it is complicated to win this game, but I certainly would bet on Pasko. Obviously the trick is to close the board with three checkers in the air, and that's not always easy. Try it yourself, and see how you do...it's fun to play and enlightening.
