3 situations to analyse:
1. Cash game. Heads up, stack 50BB each. Hero raised pre flop 3BB in the cut off. Villian and known flush chaser calls on the button.
2. Cash game. Heads up, stack 50BB each. Villian raises 3BB in the cut off. Hero calls on the button.
3. MTT early stages. Heads up, stack 70BB each. Hero raises preflop 3BB from the cut off. Villian calls on the button.
Considering you are both playing with only 50 BB effective stack, I will assume this is the NLHE micro-stakes.
You can certainly jam the flop OOP here but I don’t believe it would be optimal: we use to play cash games having 100 BB effective stack, the whole cash strategy is based on deep stacks, and I’m really inclined to agree to your choice, once you are shorty stack, the
odds are different, and pushing on the flop wouldn’t be a bad idea at all.
The problem of pushing on the flop is that you give villain a chance to easily fold its losing
hands and call only with hands having great
equity.
If I was playing deep stacked I would have checked this flop OOP, because this is the action I do most of times when I caught myself out in scenarios as you described, in spite of hitting the nuts or not hitting anything.
If your villain is a known flush chaser, I would wait for the turn to see if it completes or not. If your villain is indeed, a flush chaser, it will call a jam on the turn having less than 20% equity for the river.
And in the case villain completes his equity on the turn and comes accelerating the pot, you can easily fold dominated hands.
For MTT’s I won’t risk a comment, because I don’t like talking about things that I don’t fully understand. Being aware of the basics of tournaments, I wouldn’t recommend jamming the flop in a situation as this, specially if it is the first level of blinds. But as I have said, I play only
freerolls, you should look for players that use to play more these style.
