Jerome Gambit: One More 'Bot



I have been enjoying the YouTube videos featuring Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) games against various online computer personalities, e.g. the Play Magnus [Carlsen] botthe Fabiano Caruana Botthe Aman Hambleton bot, and the Ian Nepomniachtchi bot

The 'bot play often takes turns that I would not expect, which makes it even more entertaining.

My most recent discovery is a video of the Jerome Gambit being played against a bot personality, "MrBeast", rated 1100, by Entertaining Chess Content (creator of the GM Hambleton bot video).

When even free chess engines can destroy the average club member, how do you modify one so that it plays at the 1100 level? I suppose you could seriously limit it's "thinking" time, or have it rank-order the possible moves in any position and chose the 3rd best, or tweak it so that it plays its "favorite" piece much more often than the situation calls for.

What to you think is going on with the MrBeast bot in the following game?


NN - MrBeast bot

Chess.com, 2022

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+  

4...Kxf7 5.Nxe5+ Ke8 

Remarkable restraint for a beginner, who might have been counted on to grab more material.

6.Qh5+ g6 7.Nxg6 Nf6 


Attack the enemy Queen when possible - but this is an okay idea here. Black has to return some of the sacrificed materail, anyhow.

8.Qxc5 hxg6 9.f3 Rh7 


This is a bit odd. Perhaps we have found MrBeast's favorite piece?

10.d3 Rh4 11.Qg5 Rh5 

See notes to Black's 7th and 9th moves.

12.Qxg6+ Ke7 13.g4 Rh7 


14.g5 Qf8 15.gxf6+ Qxf6

Disastrous. 

16.Bg5 Rf7 


17.Nc3 Ke6 18.Bxf6 Rxf6 19.Qg8+ Rf7 20.Nd5 Ne5 21.f4 Nxd3+ 22.cxd3 Kd6 23.Rc1 Rxf4 24.Qg6+ Ke5 25.Qg7+ Rf6 26.Qxf6 checkmate


Ouch.

(If you liked that game, you might as well check out the quickie video "Crushing a 700 with the Jerome Gambit". Double Ouch.)
