Why you are so rude with these pals?
When I see a man playing as a 1200, I say to him he plays like a 1500.
I leave my bad feelings only for those that plays 2600 and so are lot better than me. :-)

Something is clearly broken in Deep Sjeng handicap mode because no player at level of 1401 will play moves like 11...Nxc2+

It is possible to simulate 1401 level of playing strength by making that blunder and playing later like a strong player(playing like 1700 player after blundering a piece is enough and you do not need to play like a GM) but deep sjeng does not do it and it continues to blunder also later when it miss a draw against you.

32...Kf6 could be enough for a draw after you blundered by 29.g7 and 30.Kg5
29.Rh8+ was a simple win for white and there are more blunders by both sides that I do not mention here.

I hate to defend, as you can see I am constantly attacking and going after pieces. Also I have a hardtime checkmating an opponent before the end game. ( know how to but if you look at my clock I probably only used around 40 seconds for the whole game due to lack of patience. Ofcourse I know that more than half of the moves that I played were blunders.
