JC is the button.

I’m annoyed that I’m slightly down. After my big lead early on, a couple pots and missed flops have whittled away my lead. I look at my cards and decide to play.

JA folds, MA calls, I call, JC folds, EM calls, JB checks.

Flop: K K 4

EM checks, JB checks, MA bets, I call, EM folds, JB folds.

Turn: K

MA bets, I call.

River: 2

MA bets, I raise, MA calls.

I take the pot (9BB).

What did MA have? For that matter, what did I have?

I’ll post the answer in the comments section in a day or so.
