It does happen in real money
, but not as often, seldom actually.
Do not take these situations personally and decide you have to do something. I can still remember a play money situation from many years ago where I was sitting direct to the left of such a player, who was shoving EVERY hand and played no hands until it was HU, Of course by that time he had the massive stack, and I had little chance of winning it. Odd that I remember a play money SnG..... well maybe not so odd.
Under normal circumstances you want to wait for great cards. It might help if you get it all in before he does.
If it is a variety of players at the table who seem to be taking turns at buying the pot, it is different than the single bully. In such a case, it is how these pots are won at that particular table.
I suspect these are the min size buy-in games. As you increase the buy-ins, even at play money tables, the aggressiveness tends to get toned down... a lot.
Referring to them as practice games is nice. So practice things at these tables. You practice being that bully over many tables to get a decent feel at how successful these 'tactics' are. While practicing different styles, remember that at the low stakes play money tables the results mean little. At the highest buy in play money tables you should expect play to be near what a low buy-in cash table provides.
I am a tourney guy, and I am less sure of how play money stakes relate to real money ring games.
