Performance of almost 2800 in a tournament is better performance than losing 3.5-2.5 against kasparov in a match and the difference between losing 3.5-2.5 and winning 3.5-2.5 is not big. The fact that the opponents did not prepare against tiger14 changes nothing because kasparov also could not prepare against deeper blue. The 2 losses of kasparov came from mistakes that kasparov usually does not do against humans. Resigning in a drawn position never happened to kasparov againat humans In the last game kasparov played a move that he considers as a mistake based on his book. It is clear that he got into a line that he was not ready to play and the fact that he started to think in a known position(a position that was played in the past) is a proof for it. Uri
