In general it's a pretty bad idea to fold full houses in NLHE even multiway.
having made some pretty ridic folds in low level nlhe myself....
Just to double check - board is rainbow???
I would be looking at the hand like this:
1. We have a very strong holding on a board where not only is it tough to have the good hands but its easy for people to overplay mid strength hands such as 910/ AA.
2. There are such things as coolers in poker... yes it would be sweet to fold and be shown J9... but it hurts more to be shown AA and AJ.
3. We are 4 handed... this is just too strong to fold. Even their value range here does poorly vs us.
4. Because of the stack differences we are close to 'freerolling' the shorter stack if he ever has us beat.
in short - not folding and pretty happy about it.
We will be raking in the whole pot most of the time... and for a spin from 135 it will be a good night indeed!!
