I'll make this a 3-part question.
This is the Monster Stack NL WSOP event, $1500 buyin.
First, I will set up the preflop action. 45 minutes into tournament, 25-50 blinds, no big stack at the table yet. Nobody seems to be playing over-aggressive, and nobody seems to be a big fish. It's also early, so it's hard to get many reads yet on the players.
Characters:
EP (early position) is a middle-aged Indian guy who seems solid
EP+1 is a middle-aged Asian woman whose style is unknown
SB is a young white guy whose style is unknown, but does not seem overly aggressive like you might expect a young player to be
Game is 10-handed.
EP opens to 150. EP+1 makes it 500. You are in late position, 2 off the button, and find TcTs. You decide to cold call.
Folds to SB, who also cold calls. BB folds.
4 players.
Flop: 8d 7c 6d
SB checks, EP checks, EP+1 checks -- all fairly quickly without thinking. You are last to act.
You fire 1k.
SB then check-raises to 2500. EP quickly folds.
EP+1 looks confused about what to do. Finally she cold-calls the 2500.
What do you do here? It's 1500 more to call, the pot is now 8000, and you have almost 14k behind. EP+1 has you covered by about 3k, and you have SB covered by about 3k.
