River spots, one after another, for sixty seconds. You are facing a bet and the only question is fold or call. Each spot states the range you are up against, and your decision is graded on the blinds it gave up against that range.
You will not be told how you did until the minute is over. Knowing would let you play the feedback instead of the board, and nobody turns their hand over at a real table.
1 or F to fold, 2 or C to call. Space to start.
