No stats so can't help there...
I decided on the river that ch/c was not ideal since he ch/b all his showdown stuff and only bets 6x. So I'm neg freerolling vs a 6.
In terms of his range, I think he can maybe sigh call off with 9T/8T or s/thing. I think he raises a str8/2pair before now so it's only 6x that im worried about being behind.
I was thinking that hands like Tx make much more sense for call/call line than 6x because he's drawing to the nuts, so i don't think he has that many 6x compared to all the other stuff that might hero.
It's obv gross OTR, b/c betfolding 300/400 leaves so little behind that I think ch/f would be better since we at least have a playable stack that way. So although I agree that it's tough for a non-drooler to call pot with worse, practically I'm inclined to agree with Jax that b/f for less is somehow unattractive.
Turn is interesting. I think I'm just trying to fold out his floats cos ch/f vs random QT/QJ is annoying (overally ch/f seems better I guess). But I agree that if we bet we should be bigger. Incidentally, by betting bigger I think we might narrow his river range more to pairs (on basis he folds more draws to a bigger turn barrel) so a shove becomes clearer since he has even less 6x and he gets better odds to hero 9x etc.
Anyway, I shoved and he folded. Not sure that proves anything
but thanks for all the feedback. SnG forum rulezz.
