Depends on his tendencies. Even some of the loosest fish aren't shoving with weak hands, while others may take this line with a draw. Read-dependent.
Example from a recent session of mine:
1/2 NL Live - Straddled ($5) Pot
I just switched tables because the straddler in this hand is a huge fish. I'm in the SB.
I raise to $25 with
Straddler calls (I expect him to call with literally ATC to defend his straddle). Heads up.
I bet $35.
I know from previous experience with him that he tends to raise top pair, so his call makes his range draw-heavy.
I bet $50.
His range is almost all draws here.
Straddler bets $150.
I check here because I don't expect to get any value out of missed draws with a bet. But I know from previous experience with this player that he will bluff missed draws frequently.
I call, and villain shows
There is an example of a range that is literally 100% preflop, yet we can use postflop tendencies to narrow his range and get value from bluffs on the river.
Remember, we are betting/raising/calling against a players range, not an exact hand
. So if a player's range is extremely wide, it's also generally pretty weak and we want to bet for value with solid hands. We don't need to know the player's exact hand to make correct decisions.
