How do I stop being so reckless in my games

Despite being able to easily beat 1200 bots or people I know in real life, I get incredibly reckless and nervous against low rated players, and in most games, I have played till now I do moves in less than 10 seconds, is it just "beginner" nerves or is it something else? I should also add that in my entire life I've played around 50 games, and I've only played seriously around 16 of them.

So first of all:

a 1200 bot is like a 700 rated person. Any bot plays about 4 or 500 points lower than advertised. I used to think i was better than I was when I was beating 1500 bots easily, and beating 1800 bots on occasion even ... until i started playing people. That was quite the wake up call. I was struggling against 900 and 1000 rated real people. I wondered why until I did some research.

The bots on here or anywhere else are just really generous estimates of what their strength is like. Bots don't really play like the level they are designated at, because its incredibly hard to emulate how a person plays. So, the only way they can try to make a bot play like a person, is make a 3200 level bot screw up on purpose. thats what any bot under 3200 does. The further away from 3200, the more egregious and random the error is.

as for people you know in real life, unless they have a history of playing chess seriously whether in a school, club, had serious instruction with a high-rated player, they are waaay below the average person online. I think the average person who knows how the pieces move and plays anywhere from once to several times a year would be rated 400-500, somewhere in there. 

So, my point in writing all this is yes, nerves could be affecting your play but you also have to realize its possible you are inflating your chess ability as well. Which is fine, no big deal. The next step is to keep learning, keep playing, and eventually you will become more confident and better skilled and you will find the easy-to-avoid mistakes will become less and less too.

For starters bots rating is heavily inflated and are not a good opponent to play because they will play really solid then make a ludicrous move. With that out of the way lets talk about chess recklessness.

You should really spend more time on moves especially when you have the time to play those moves. When you spend more time on moves you will see what moves might be bad and what can be good thus improving your accuracy. Over time this will pay off and whats difficult for you now might become easy for you later.

Also before making a move try to figure out how your opponent will respond and whether or not this resulting position is favorable. Make sure you do not play hopechess, what i mean by that is dont play a move in hopes that your opponent will blunder. Consider what will happen when your opponent doesnt blunder. 

Lastly look at what your opponent is doing. What was the purpose of their move, i remember when i was 1000 the games would end with whoevers plan was faster and more successful without either player trying to stop the others. That is not what you want to do, try to understand your opponent`s move and decide whether you should stop it or continue with your own.

I hoped this helped, feel free to message me with more questions related to chess.
