so a pretty standard hand untilll the river.at this point i put him on a strong king, or weak ace. and i know if he feels i have him beat he wont give up on a big pot. so i put out bait, a huge underbet, a poisonous blocking bet. i wanted to fake fear of this flush and big cards on board. he ate it up and moved in. hell do this if he misses a huge draw too. if i value bet here i might not even get a call and i for sure wont make a lot.
