Whats the difference between 1100 and 1200 in real life

is it just tactics?

Over the board? Blitz? Bullet? Daily?

It doesn't really matter.  There is no objective list of skills that a 1200 has that an 1100 doesn't.

Whoever's paying attention more... They're both atrocious.

i noticed that 1200 make less blunders in real life and play with a plan

in standard

bb_gum234 is right. I reached a rating of 1800 with little to no efforts besides tactics, tactics and more tactics. Once you reach a certain level with tactics, you can't help but notice certain strategic patterns anyway. So, it is not lagging very far behind my opposition. The biggest difference between any two players at amateur level is going to be their tactical ability. Only at the higher rating levels do other factors not just become relevant but even extremely important.

Even if at a certain level before titled play strategy becomes relevant, it is usually pure calculation and "missing" certain moves or not that determines who gains the strategic advantage, rather than "understanding" or other similar intellectual concepts.

The difference is, 1200 player should be able to score 64% against the 1100 player by generally playing better moves and blundering less.

100. Sorry but someone had to.

lol...
