How to beat the Jonas bot?

Sort:
KevinOSh

There is an old guy at my chess club who plays just like the Jonas bot. He starts off with dubious openings and then gradually complicates the position until I make a blunder and then he goes on to win.

The same thing happens to me with the Jonas bot. I have beaten all of the other bots up to Arthur, what kind of things do I need to do to get over this next hurdle?

Please don't just tell me not to blunder, as that's not very helpful. What I am hoping for is someone to say "I struggled with that as well and then I studied this and that and then it was easier.'

It seems you like simplified positions. Try to trade down, probably, and get into a more simplified middle- or end-game. 

KevinOSh

I do prefer simplified positions but stronger players generally don't trade down unless it improves their position somehow.

What’s Jonas’s rating?

EDIT — never mind, found out. What is your clubmate’s rating?

About the same strength as the bot. 1400 classical/1500 rapid.

I play out the openings entirely on general principles. The computer evaluation says I am slightly better but I never actually get a material advantage. Then I reach a middlegame position that feels like I have been transported into a new foreign land.

From what you've written I gather that your nemesis is a better player than you are, and that is the reason why he wins. Not a lot better, only a bit better, but even that can lead to lopsided results, see for instance the Carlsen - Nepo match.

Having a slightly better position out of the opening does not mean much, especially in blitz chess. Openings matter very little, blunders matter a lot. Try to not blunder, or at least blunder less.

The good thing is that you are improving rapidly, and your opponent presumably isn't. Just keep doing what you are doing, and in a few months you will be the better player.

Has anyone here beaten the Jonas bot?

Unfortunately I only play the free bots so far.  However, if you post a typical game of yours against it, we could take a look.

For example, in your most recent game against Jonas, it looks like you missed the fact that his 14th move attacked your rook.  Based on this, I think you need to make sure you see what your opponent's move is doing, and in particular what attacks he is making, before planning your move.  If you'd seen his attack on your rook, you could have interposed your queen to offer a queen trade, for example.

Good game, well played

I played him again and got a draw. Should've won but blundered the rook and pawns endgame. Jonas is definitely beatable but puts up a tough fight when behind.

I just beat the Jonas bot and did a google search and found this thread lol. I'm not sure what the policy/etiquette on this forum is for replying to old threads but I figure it can't hurt so I'll share the game I played! No timestamps on pgn unfortunately but I played the game like a standard 10 minute rapid time control.  I also had never played the Jonas bot before so I had no idea how it would play against me.  In my opinion, this bot is definitely beatable if you stick to a solid opening and focus on positional goals to achieve during the game. I'd also say that you don't need to worry about knowing theory to beat this bot. I had no clue what theory was when i played it and clearly messed up the opening i was trying to play (Benoni). Overall, I believe that an average strength player (1200 rapid on here) could beat this bot if they just play positionally solid long enough to get an advantage.  The only thing i would address to be careful about while playing this bot is that it seems like it relies on it's tactical abilities to win games. Fortunately, it also seems to completely disregard any strategy that doesn't equate to immediate tactics for itself and will create weaknesses for itself without you really doing anything because of how hyper-aggressive it plays.  You can actually see in my game right after what i consider the opening phase of the game that it seems to implode on itself without me doing anything!  The rest of the game was a cakewalk for me.  This bots game-plan seems to be purely to try to attack and create weaknesses for the opponent no matter what the cost.  It wants to use tactics to win the game sooooo bad lol. My advice is that you should avoid complicated positions (you probably wouldn't want to play a gambit as white against this bot) against this bot since that is only doing it a favor. 
Before i finish i would like to add that I wasn't ever trying to hype up this bots tactical abilities since I think it probably posseses what I would consider "intermediate" tactical abilities that aren't going to be too hard to spot/prevent.

I just beat him first try, just gotta get him off balanced in the beginning and look for trades while also strong making attacks
