The big blind is one of the most important positions to master in tournament poker — you are forced to post a full blind without seeing your cards, yet the pot odds demand you defend with a wide preflop range and play out of position postflop against most players. Get it wrong and you either underdefend, allowing opponents to profitably steal your blind, or overdefend, setting up difficult postflop spots out of position.

This advanced Texas Hold'em preflop poker quiz tests your big blind defence strategy across 10 borderline scenarios — covering open raises from early position (UTG), middle position (HJ) and late position (BTN) across deep stack (60bb), mid stack (30bb) and short stack (15bb) situations.
