very often.i stick to h/u or mtts nowadays to avoid collusion . but just played a 20 d double up as i had a bit of time o kill. on the bubble a guy shovesfor 600 from sm 200/400 and big stack in bb passes for 200 more lol. next hand bb is back to raising hand as hed done pretty much all the time earlier.clearly chip dumping thankfully u dont have to suffer that cr4p h/u and rarely in mtts.
