It sounds a little like that spot where the weaker player, in addition to his usual pocket,
gets an extra side pocket?
Spidey has an extremely entertaining post about that kind of 1-hole spot.

In fact, Spidey got all 3 pockets on his side of the table (both corners and side).
So he had 3 pockets to the opponent's 1.
The short version is: it's a trap. The weaker player will never get a decent shot at those extra pockets.
Not when you're playing a champion.
This is spot on and has been my experience playing a champ. They will absolutely suffocate you with lock 'em up traps. I never played with a spot, even a world beater, but then again I didn't win either - not even close. In a game like onepocket, almost everything that the weaker player does will be executed better by the champ and the result is that after a series of safes, the champ ends up with the one that locks up the rock in prison and forces the other player to take a foul or to sell out. There is usually no future trading fouls with a champ, imo, so one is inclined to take a flyer, as that is all that is left any way. And one can't win games shooting low % shots exclusively...
