Final Pot: $42.50

Lead for 2/3 pot on every street. Only K9 and AK beat you, and AK is unlikey (because it would raise prf on the button).

YHIG 99.5 percent of the time. Valuebet every street.

Bet like you're up against set/2p/oesd. Bet 3/4 pot every street. Forget about K9/AK.

What ^ all said

Any 8 9 10 J Q K, or A really sucks on 4th or 5th street. you are very lucky they both bricked. As others have said, play this more agressively.

edit: gonna buy hooked on phonics or something
