SB: checks


The guy was 45 9 and checked the river pretty quickly. Problem is that it's hard to come up with weaker hands that call me here. I have all the tens, so unless the guy somehow has a jack or king, it's very hard to expect a call, and of course even if he has a ten he's not super likely to call. Meanwhile I feel like people don't checkraise the river so much when the pot is this big compared to the stack sizes, but perhaps it's hard to say this about someone who is 45 9.
