Preflop Poker Quiz
Opening ranges, blind defence and why position decides so much: which seat opens widest, how tight Under the Gun should be, why the big blind defends far wider than it opens, which opener it defends widest against, why limping from the small blind is a leak, and what to do when your cutoff open gets 3-bet. The reference widths quoted in the answers are the same tight-aggressive baseline that grades the GTO trainer — calibrated to published 6-max 100bb charts, not live solver output. There are 8 questions; scoring is instant, and submitting reveals an explanation under every one of them — the ones you got right included.
