Here I'm up against an unknown opponent who seems fishy. Over 40 hands he's playing 50/10 which means we know basically nothing. We can suspect that his 3-betting tendencies will lean more towards those of other loose/passive players (perhaps 10-7% 3-bet range vs the BTN).
$0.25/$0.5 Fixed-Limit Hold'em (5 handed)
Preflop: Hero is BU with 8:c, T:d.
2 folds, Hero raises, SB folds, BB 3-Bets, Hero calls.
Flop: (6.4 SB) Q:s, 4:d, T:s (2 players)
BB bets, Hero calls.
Turn: (4.2 BB) 2:d (2 players)
BB bets, Hero calls.
The flop and turn are fairly standard lines. For more information on calling down when you might be behind see this thread.
River: (6.2 BB) J:s (2 players)
BB bets, Hero calls.
This river card is literally the worst in the deck. It improves my flop & turn calling draws to at least 1 pair. My made hands like 77-99 and TX may have fallen behind and KJ/J9 may not be ahead either.
I'm getting ~7:1 though and so I only need to be ahead about 13% of the time to make this call correctly. Deciding whether to call or fold depends a lot on our opponents preflop 3-betting range and turn/river barreling tendencies.
Should I call or fold? Why?
