Hi! My friend who started playing chess recently, asked me if I can give him some weak engine so that he can also learn chess by playing against weak engine. I was trying to find some of them online, but all those are too strong, 1800 for example is too strong for beginners! So, my question is, can you tell me names of engines from 1000-1800 elo or even better links so that I can download them and see if they are ok or not for my friend. Thanks in advance. Regards!
