I do not claim that I do not blunder and I do not claim that I never blunder by
something that computers need a short search to avoid.

The point is that I usually do not blunder by something so simple like kramnik
did when computers needs one ply search to see that a move is losing a piece and
you only need to calculate 3 plies forward after your move(check escape
capture).

Here is an example of one of my blunders that is slightly harder to avoid than
the blunder of kramnik.


[D]6rk/1p1Q3p/1qp2p1N/4p3/1p2P3/3P1PbP/2p5/5R1K b - - 0 30


I played Bf4 and lost because of a forced mate when Qf2 was winning.
I simply did not see on time Nf7+ Kg7 Ng5+ Kg6 Qxh7+ Kxg5 h4#

The main problem was that I did not consider Ng5+ because g5 was so protected
but you need to calculate 5 plies forward after Bf4 to see Qxh7+ to start to
suspect what is going on when Kramnik needed to see less plies forward to avoid
his blunder.

I thought also about Qf2 in the game but did not see that it is winning and
again more than 3 ply search is needed to see the final result of it and I had
not unlimited time so I had to decide about a move.
