Who is Who Marta Marco
The rationale for this play is that, like many players, this opponent will fold his mediocre hands if you bet on fourth street to avoid having to call twice to see what you have. Your checking on fourth street makes it easier for him to call on the end, not only because you have made it cheaper but also because you have shown weakness.
Obviously checking is also the better play that 25 percent of the time you have the worse hand. Finally, checking on fourth street induces a bluff on the end. Beware the man who would sell thee a system; if thou knowers a profitable one, preserve it to thyself in silence. Your opponent, who is a good player, checked and called your bet on the flop.
When the deuce falls, your opponent checks again. Should you check or bet your pair of kings? In hold ’em, any time an opponent bets, calls, or raises, good players ask, “What could my opponent have done that with?” Then they think of the various hands the opponent might have to do what he did. So when your opponent called your bet on the flop and then checked on fourth street, you try to determine what hands he might have that prompted him to play the way he did.
