Whats your OTB rating?? Online people make dumber mistakes than they do OTB. It proves nothing to get a high chess.com rating if your otb is low.
I have never played a single tournament game OTB. As you can see I started playing chess less than six months ago, so I'm only practicing yet. I also wrote earlier that I would like to play some OTB games eventually, but haven't had the time to get in touch with local OTB chess community. I will do so in the future. For the time being I quite enjoy practicing this game online, and will aspire to play some OTB chess in the future.
