$2.25 turbo QT

I would probably check/raise instead of donk, but as played I think stack off is fine. Our hand is quite strong against Tx, draws and semi-bluffs.

why is check raise if better then donk on this board????

Because I think he would cbet bluff a decent amount on this board. So, if we check/raise, we get more money when he decide to do that. If we donk, he probalby just fold those pure airs.

can u make a calculation of the chip again with air

and the chip again with the expectation value of range range call raise with vilain range

because i think either my math is off or yours

i think i gain more chip by donking ♠_cool:

especialy with this type of board

I think donk is not too bad against some opponent at low stakes. It is hard to calculate the expectation on flop since we need to consider what happens on turn and river etc..
So, suppose villain has some weak hand, we donk and he probably folds, and if we check, he will cbet and we raise he folds, this way we gain mb 2-3 more BBs.
If villain has some good draws or top pairs+, then we probably will stack off on flop no matter what we do.

If villain has 5x or 8x, I expect him to bet/call check raise in 2nd case and call our donk in first case. So, we get more chips in pot by check/raising than donking.

But this is what I expect from a typical villain. However, if you have read that he might check back draws, small pairs, then it is probably better to donk.

So, in general, if you expect villain to cbet a lot, you should check/raise, and if you expect villain to check back a lot, you should donk. In my opinion, villain would cbet enough on this board for us to check/raise. But I haven't played 2s for years, and maybe the typical villain at those stakes are different.
