Thank you for posting.
Firstly, I would say you should fold pre-flop. If SB just calls the min-raise, then sure, you can call because you close the action and don't face the possibility of another raise from CO or BTN.
Now let's get into CO's "imaginative" play...unfortunately there are going to be players at all stakes that are playing for various reasons. Especially in the early stages of
freerolls, some players are going to goof off in the hopes that they build a big stack early and give themselves a half decent chance of cashing.
Pre-flop: 42o is never an open here, even more so when you are the short stack with stacks behind you ranging from 67bb to 170bb. What's impressive is that the open isn't even their worst play, but they then choose to min-4bet with 3 players still in the hand.
Flop: They obviously don't catch very much of the flop. If SB bets smaller, I wouldn't be totally against a
bluff shove here with the BDSDBDFD, but when SB bets half pot, he has almost no fold
equity. Calling is literally the worst option he could choose here.
Turn: The turn doesn't bring a 3, 5, 8 or diamond, so all the back door outs have now evaporated. If villain had a larger stack, jamming wouldn't be the worst here when SB checks, because the 89 gets there and hands like QJd/c have just binked a whole load of extra equity, but when villain is shoving 12bb into 33bb, SB should be calling with any T or better and all the good draws.
In summary, although it's obvious that villain played this hand just about as badly as it is possible to do so, who really know their motivation behind playing this way? They could be drunk, on tilt from a previous bad beat, punting early to build a big stack, just testing out the site, got something else they need to do, so just punting before they give up. The good thing is, you have the opportunity to make a note on this player, so that if you see them doing something similar in the future, you can call them much lighter than you otherwise would, because you've seen them do this. It's great information to have and you want to be playing against this type of player more often.
