Junior understands that a draw is obvious but Fritz can't accept draw with two pawns up. 0.00/18 41 57.Kb4 150 Td7 1475kN/s 0.00/19 538 58.Sb6? Just not only blunder but a positional mistake as well. Easy to see that white can't improve its position. Pawn "a" should protect knight b6 all the time and can't move. Now black attacks white's pawns in the kingside.0 Td3 Here, White is probably in big troubles, maybe just losing. Two pawns up, but.. .. King is a nice target for the black bishops. -0.59/17109 59.Lc6 168 Tb3+ 1425kN/s -0.68/19 180 60.Ka4 0 Lc5 1318kN/s -0.68/19 91 61.a6 Fritz gives a piece, but Junior's technique this time was good enough to realize this material advantage. 99
