Discussion about the Britvachka-Valenok party.

If the opponent isn't playing very well, it's quite possible that they haven't cleared out the treasure locations properly. Even if it's a strong player, there's still a chance of this happening, as in that case, the opponent usually tries to control the center early on, which means there's still hope of finding something hidden or unclaimed.

Keba did something similar in a famous game against Britva, which confused his opponent (he stole a Pandora's Box with a 4th-level creature). The situation here is somewhat similar to that.
