Why 1200 are better than 1500 +?

The main problems I see are the blunders on moves 19 and 21.

@azuaga #20 What's the minimum rating to be eligible to play with you?

Azuaga, yes! They say same on my chess club.

@hangrad 1050 or less is well for me

😯 azuaga, you are 2000 and 1200 can beat you?

While he may have exaggerated the number of games he has won against higher rated players, I understand what he means about many lower rated players being difficult to beat in Blitz. It probably has a lot to do with the following reasons:

1) They're used to the time control. Even in rapid many players are in a habit of playing too fast, which increases their level of play relative to other formats (but note that this is not necessarily good for overall chess improvement, as recounted by many professionals).

2) They don't play blitz often and have low ratings from when they were beginners.

@BigGreenShrek
I see but i was scared of he block my queen. My pawn was running alone on the border and it was (i think) interesting and can force him to wont move his rook for cover the queen promotion.

@azuaga you should play only good players. 2050 and up. They will make only good moves and you will easily beat them all. If you play lower rated opponents, they might not know the theory and get you out of book. It's much easier to beat high rated opponents then low rated ones.

Rey pato, i totaly agree 👍😀. How can i progress when players move very fast?

@Flavinou Being "scared" is not a good excuse for playing blunders. Calculate the variations and determine whether or not the move is good.
