we don't know nothing yet about him? I just call him down to get informations and see what he did and why then...
perhaps he's the kind of player who gets excited when makes top pair on the river... or the one that uses any big scary card...
or even worse he made is hand on the river or was slowplayng one and if comes over the top we'll be wondering what the hell happened
we are probably missing value here but we could get valuable information in exchange...
