Tournament play is the very pinnacle of backgammon. Good money players don’t always make good tournament players. The converse is also true because some players who excel in tournaments can’t cope with the financial pressures of high stakes money play (particularly chouettes). In a tournament once you have paid your entry fee you are free to play with no additional financial pressure.
To re-iterate a key point – the score dominates all other aspects of tournament play and as we progress we will see just what an influence that can be on play and doubling decisions.
