I probably would give them a quick kind rundown - I would be careful not to aggravate other players . After all there is online poker schools . I for one would not enter a huge tournament table not knowing how in the world the game is played . It will be their loss eventually if they didnt go study something even if no one answered there questions. Not alot of players give up there strategy - It is poker man what are the chances that you will belied to by some unforgiving player ??
