Nice to see you on here. There are a few BJJ places in India. There is one place in Mumbai that has a 10thplanet blue belt (rao?) come out there every now and then and teach (I assume he is visiting family).
I am Pedro Sauer Blue belt and Japanese JJ purple belt and have recently moved to India. I currently live in Banbassa and am teaching BJJ to the kids here at the orphanage. If I get a chance to come to Delhi I will let you know so that we can train a bit together. I am trying to get some mats. Rolling on concrete really sucks :-) We did it for a while, but it got too uncomfortable.
