In israel players who start to play in tournaments get 1350 elo rating and only
if they lose they can get 1300 elo rating.

1300 is the minimal elo rating and they cannot get a lower rating even if they
lose so I think that 1300 players often do not see 1 ply forward.

They may sometimes see 2 plies forward but it does not compensate for the fact
that they often do not see 1 ply.
