chessmaster continued to consider the same stupid line after more than3 hours do
I told it to play and it played e7 so it did not solve the endgame after more
than 3 hours.

programs are weak in evaluating passed pawns and this is the reason that they
have problem to solve this endgame.

after h6
chessmaster wanted Kc8 and after 4:22(means 4 minutes and 22 seconds) it
understood that white has 0.45 pawns advantage so it changed its mind to Rb1+
after 12:24 with a draw evaluation
Rb1+ Kc2 chessmaster needed 3:59 to see that Rxb5 is not winning and it
understood that white has 0.82 pawns advantage.
