I went to a casino today for the first time and played some 2-3-5 spread limit. Live games in the Bay Area have a weird structure where the big blind is $5, the small blind is $3, the button posts a blind of $2, and it's $10 to call pre-flop. Also, the maximum bet or raise on any street is $200 (if it's checked to you, you can bet up to $200, but if someone else bets $100, you can raise to $300 for example).

The game has your usual mixture of maniacs, loose passive players, and grumpy old nits. I'm dealt 77 UTG at a 9-handed table and I just limp for $10 because I don't want to play a 15-way raised pot in crappy position with 77. The flop ends up being 4-way with these players.

BB - biggest fish at the table. He plays every hand and makes random bets that seem unrelated to either his cards or the size of the pot.
UTG - me
MP - unknown who just sat down
Button - maniac

The flop comes 665 rainbow and BB bets $10 into a $40 pot, which means God knows what. My position kind of sucks but I'm not folding any overpair to the table fish for 1/4 pot so I call. MP calls as well and Button folds.

On the 3 turn the fish bets $40 into a $60 pot. If it were heads-up I'd definitely call and I might even raise, but I still have no idea what MP has. Being squeezed between the fish and an unknown player I wasn't sure what to do, so I just called hoping to show my hand down cheaply. MP calls again.

I don't remember exactly what the river was but it was a total brick, like a ten or a jack or something like that. BB checks. I feel like if I check and MP bets I'd have to fold, but I'd like to get a little value from the BB if he has Q5 or ace high or some such nonsense, so I just bet $50 into the $160 pot to block MP from making a bigger bet, and hopefully get value from the BB. If MP were good he could probably raise me here with any two, but the passive line he took so far makes me think a raise from him isn't likely.

How'd I do?
