what do you think?

i'm believe he's hit a lucky card on the turn but my odds were to good to fold. do you think i played the hand fine after the flop?

i knew that my opponent was an idiot before the hand. he could have had the 6 or even a 2 or a 4.
a few hands earlier (10-20 hands before this one) he called a bet on a board of 789T with 74. the board was double suited and he had no draw. he also called a bet on the river and they were not min bets and 4 players saw the turn.

preflop i wasn't too sure what to do. there were already 2 extra players in the pot because they had just joined the table. i made quite a large bet. should i have bet smaller to keep the pot small? or is the bigger bet good because it drives out all the crazy fish at the table?

Easy call.

I would have made it ~ 1.5 preflop.

[NLHE lahooozaher]

Easy turn call. I would have also raised less preflop but it's fine after that.

2 players posted their blinds this hand so pot starts at $0.90, I like the raise to $2.
