Well i reckon for a start he would probably be playing in the biggest online game possible so you would have to be rich or stupid(or both) to "call on anything".As far as his maths skills...they will obviously be the same,perhaps become even more important online with RE value betting etc.Also his fantastc memory would also come into play alot remembering different players styles of play and deducing what hand his opponent holds from betting pattens over a number of hands.Its probably a very good guess that he would be a big winner at internet poker IMO!!
