Notes on villain- Older asian lady (50-60), tight and very passive. Looks like a clear value bet after she checks 3 times. Thoughts on my turn sizing and value sizing now on river? I think she has worse hands that will call: A10x, Axdd, 56, 10x8x. I don't expect this player to ever hero call with a one pair hand that isn't Ax. Thanks for feedback!
