That's my conclusion based on last night's game.
With four players, a hand quickly descends to a heads up game, usually because the two blinds don't want to forego their chips even though everyone else has folded. And that's a real limper of a hand, with round after round of no-bets as the remaining two just check their way through to the River.
Last night, even with three or four players in a hand, there was too much nervous checking going on to make many of the hands desperately exciting.
And no bloody All-Ins, if you can believe it.
