That "trick", as Sanny calls it, is standard practice in all

exchanges and mating attacks.

Yes your technique is good but the way my programmers implemented it
reduced its depth to 2 level deep. So When there is a move with no
Check/ Capture it played the moves with just 2 level depth. and it
lost all the matches it played.

Now it has been removed. And it will be done soon again with better
technique. as current implementation made it play very bad.

Implemented *correctly*, this technique I would expect
adds hundreds of rating points worth in tactical strength;
done wrong, it is impossible to determine the potential
damage. You see, unlike stupidity, genius has its
limits.

Play a few games with Easy & Normal Level & see if it needs Check &
Capture. If yes then it will be again added but this time using a new
method that will not reduce its depth of search.

How? I am still fighting for my life in a position
which should have been detected by the program
as an "insufficient mating material draw". I can't
move, I can't resign because it's not my turn, and
I can't lose unless and until another fluke auto-
termination occurs, zapping my rating like before.

Somewhere on the 'net there are articles which
explain precisely how the check-and-capture
extensions work, and how to implement them.
If I had the expertise, I would explain it here (or
rather, in rgc.computers) for you. To put things
into perspective, back in the 1980s there were
tabletop chess computers which would give the
current GetClub program a run for its money
despite their having unimaginably little memory
and speed by today's standards. This was the
jump to light speed we humans had been waiting
for.
