Chopping means sharing equally like chopping the pot, when two or more players have the same hand on the river. What you presumably mean is deals. Some deals are chops but the vast majority is based on either ICM or some kind of negotiation, where the players with most chips get the biggest share. And yes I sometimes accept deals, if I have other things to do than playing a perhaps lengthy heads-up battle for the last dollars. I dont care about the "honour" of winning an everyday online MTT, since I have won many already. The other purpose of making a deal is to reduce variance, if its a large tournament relative to your bankroll.
