If all goes well in the coming months, I plan to enter some regional OTB tournaments starting this summer (my first since the 90's!) Several GM's including former world champion Boris Spassky advocated using correspondence chess as a training tool for OTB competition. This is a grey area in my opinion. I agree correspondence chess can help up to a point, but making strong moves with only 2-3 min. per move in OTB competition would seem to require some additional training at that pace of play. So, is correspondence chess all one needs to train for OTB tournaments, and if not, what additional training is required for good OTB results?
