It was actually a button straddle for$10 he called and I raised to $40 he called the rest was the same after he check raised I put him on a made straight or a naked A-H or a hand inferior to mine with or without a heart on the turn he checked with 4 hearts on the board I thought he had the naked Ace and was waiting for me to bluff he went all in on the river. He went on to win $4000 that night very aggressive lots of check raises and lots of over bets I went on to lose $800
